Dynamic (non-explicitly declared) properties are deprecated as of PHP 8.2 and are expected to become a fatal error in PHP 9.0.
There are a number of ways to mitigate this:
* If it is an accidental typo for a declared property: fix the typo.
* For known properties: declare them on the class.
* For unknown properties: add the magic `__get()`, `__set()`, et al. methods to the class or let the class extend `stdClass` which has highly optimized versions of these magic methods built in.
* For unknown ''use'' of dynamic properties, the `#[AllowDynamicProperties]` attribute can be added to the class. The attribute will automatically be inherited by child classes.
Trac ticket #56034 is open to investigate and handle the third and fourth type of situations, however it has become clear this will need more time and will not be ready in time for WP 6.1.
To reduce “noise” in the meantime, both in the error logs of WP users moving onto PHP 8.2, in the test run logs of WP itself, in test runs of plugins and themes, as well as to prevent duplicate tickets from being opened for the same issue, this commit adds the `#[AllowDynamicProperties]` attribute to all “parent” classes in WP.
The logic used for this commit is as follows:
* If a class already has the attribute: no action needed.
* If a class does not `extend`: add the attribute.
* If a class does `extend`:
- If it extends `stdClass`: no action needed (as `stdClass` supports dynamic properties).
- If it extends a PHP native class: add the attribute.
- If it extends a class from one of WP's external dependencies: add the attribute.
* In all other cases: no action — the attribute should not be needed as child classes inherit from the parent.
Whether or not a class contains magic methods has not been taken into account, as a review of the currently existing magic methods has shown that those are generally not sturdy enough and often even set dynamic properties (which they should not). See the [https://www.youtube.com/watch?v=vDZWepDQQVE live stream from August 16, 2022] for more details.
This commit only affects classes in the `src` directory of WordPress core.
* Tests should not get this attribute, but should be fixed to not use dynamic properties instead. Patches for this are already being committed under ticket #56033.
* While a number bundled themes (2014, 2019, 2020, 2021) contain classes, they are not a part of this commit and may be updated separately.

The theme includes styles for the spacer block for the front which appears to be unnecessary:
* It adds `display: block` even though that is the default.
* It removes top and bottom margin, even though this is not needed in the post content because of collapsing margins between blocks.
* It uses a custom CSS property to force a specific height on mobile. This affects the patterns in the theme negatively.
It also causes styling problems:
* When the spacer block has a height set to `0` in the navigation block, as the theme forces this to be larger on smaller screens.
* When the block is horizontal. Horizontal was not an option when this style was added.
Consequences of removal:
* Removing the use of the custom CSS property will cause a style change for websites that have adjusted the spacing property.

The existing filter `image_editor_output_format` receives an additional parameter `$size_name` which is populated whenever it controls the output format for a specific registered image size to create. Otherwise, it remains empty. In order to achieve this, a low level change has been added in bringing a new `$size_name` class property to the `WP_Image_Editor` base class, which is introduced in a backward compatible way that will not cause conflicts with custom implementations.
This parameter is then used in new logic inside the `wp_default_image_output_mapping()` callback function for the filter, controlling whether `image/jpeg` should map to `image/webp` output or not. By default, this is enabled for all WordPress core image sizes by default, and this list can be modified using a new `wp_image_sizes_with_additional_mime_type_support` filter, e.g. to remove core sizes or add custom sizes.
The customization per image size may be further enhanced by providing a more declarative API via a new parameter on the `add_image_size()` function.

This is a test fixture (dummy class only used in a test context), which incorrectly implements the magic methods.
With the deprecation of dynamic properties in PHP 8.2, this needs to be fixed.
The new implementation represents a “proper” implementation of the magic methods for a class without non-`public` or typed properties.
Notes:
* Instead of relying on dynamic properties, the magic methods now store properties in a `private` `$arbitrary_props` array and retrieve them from there as well.
* The original `$foo` property, even though declared as `private`, was never `private` in practice due to the way the magic methods were originally implemented. In effect, it was fully publicly retrievable and modifiable without any (type) restrictions. With that in mind, the `foo` property has been moved into the `$arbitrary_props` array to keep the implementation of the magic methods as clean and straightforward as possible. With the adjusted magic methods, access to and modification of `$foo` will (on the surface) continue to work in the same way as before, while under the hood, it is no longer affected by the dynamic properties deprecation.
* Take note of the use of `array_key_exists()` instead of `isset()` in the `__get()` method. This is intentional and allows for `null` values to be stored and retrieved.
* Also take note of `__set()` method no longer returning. `__set()` is supposed to be a `void` method. In practice, the return value would always be ignored due to how PHP handles magic methods, so in effect, this change will not make any difference and does not constitute a backward compatibility break.[[BR]][[BR]]
> The return value of `__set()` is ignored because of the way PHP processes the assignment operator.
Alternatives considered:
* Instead of fixing the magic methods, they could have been removed instead and the class be made to `extend` `stdClass`. It has been chosen not to do so for two reasons:
1. It’s kind of nice to have at least ''one'' correct implementation of magic methods in WP, which can be used as an example to point to as well.
2. Extending `stdClass` would change the class hierarchy, which ''may'' or ''may not'' affect the tests using this fixture (depending on what’s being done with the class). Extending `stdClass` would also obfuscate what’s going on in the class and would require extensive documentation to prevent the extension being inadvertently removed at a future point in time.
* Instead of fixing the magic methods, the test fixture could have been deprecated and/or removed, with the few tests which use the fixture being updated to use `stdClass` for their test fixture instead. It has been chosen not to do so as there may well be external (plugin/theme) tests relying on this test fixture and evaluating whether that is so would be hard, as WP Directory cannot be used, since test code is normally not included in the code published on wp.org. Also note, there is still a (deprecated) `Basic_Subclass` fixture in the test suite, which extends this class.
These magic methods and the `Basic_Object` test fixture were originally introduced in [28480] and [28523]. The fixture was deprecated in [42381] and undeprecated again in [45807].
At this time, the test fixture is used in the `WP_Test_REST_Post_Meta_Fields` and the `Tests_REST_API` test classes.

In [53164] the `clipboard.js` library was updated to from version 2.0.8 to 2.0.10, and in doing so caused a TypeError JavaScript error to be thrown when the copy button for debug information was used.
With the update, the `clipboard.js` library introduced an enhancement to its `.copy()` API, which now removes the fake DOM element used for copying content, which Site Health previously had to remove manually.
As this fake DOM element is now removed automatically, the copy function within the debug information screen can rely on the library performing the removal, instead of WordPress needing to do so manually.

These magic methods were introduced to prevent a backward compatibility break, but in actual fact:
1. ''Caused'' a backward compatibility break. The original `$factory` property was a `static` property and this declared property was replaced by the magic methods. Unfortunately, it was not realized at the time that these magic methods **''are not called for static property access''**.[[BR]][[BR]]
> Property overloading only works in object context. These magic methods will not be triggered in static context.
And as approaching a static property in a non-static manner is [https://3v4l.org/93HQL not supported in PHP], this effectively created a backward compatibility break instead of preventing it.
2. Were hiding errors in tests, as the magic methods would be invoked for non-existent properties and would return `null` (get) or `false` (isset). See [54040], [54041], and [54077] for bug fixes related to this.
3. Are problematic in relation to PHP 8.2, as the implementation is incomplete, does not protect against dynamic properties and hides PHP notices about undefined properties.
Now, there were several options to mitigate this:
1. Revert the original commit. This would be problematic, as the ''non-static'' version of these properties has now been supported for 7 years, so this would create a new backward compatibility break.
2. Improve the magic methods. With all the issues with magic methods (see the discussion in the [https://www.youtube.com/watch?v=vDZWepDQQVE livestream from August 16, 2022], this would probably cause more problems than it’s worth and would make for a much more complex implementation, which is over the top for this relatively simple functionality, especially in the context of a test suite.
3. Remove the magic methods without adding the property. This would again cause a backward compatibility break, though one for which the mitigation solution would be relatively straightforward, i.e. to replace property access using `$this->factory` with a function call `$this->factory()` (or `self::factory()`, as the method is declared as static). While we can (and have in a subsequent commit) mitigate this for the WP Core test suite, mitigating this for plugin or theme integration tests is outside of our purview and they would still need to deal with this backward compatibility break.
4. The current solution: removing the magic methods, explicitly declaring the (non-static) property and setting it in the `set_up()` method. This does not constitute a backward compatibility break with the functionality as it was over the past 7 years. Setting the property in `set_up()` may be “late”, but that is the earliest place in which the property can be set as non-static. If the factory would be needed prior to `set_up()`, the (static) `WP_UnitTestCase_Base::factory()` method should be called directly. This is no different from how this functionality behaved over the past 7 years.
Note: The property is straight away marked as “deprecated”, since the method should be favored over the use of the property.
