Weston Ruter 84d2c51153 Widgets: Add shortcode support inside Text widgets.
* Used now in core to facilitate displaying inserted media. See #40854.
* The `[embed]` shortcode is not supported because there is no post context for caching oEmbed responses. This depends on #34115.
* Add `do_shortcode()` to the `widget_text_content` filter in the same way it is added for `the_content` at priority 11, with `shortcode_unautop()` called at priority 10 after `wpautop()`.
* For Text widget in legacy mode, manually apply `do_shortcode()` (and `shortcode_unautop()` if auto-paragraph checked) if the core-added `widget_text_content` filter remains, unless a plugin added `do_shortcode()` to `widget_text` to prevent applying shortcodes twice.
* Ensure that global `$post` is `null` while filters apply in the Text widget so shortcode handlers won't run with unexpected contexts.

Andrea Fercia d35be7a120 Administration: Admin menu: Use `aria-current` for the current active page.
The `aria-current` attribute is a simple, effective way to communicate to assistive
technologies which the current item within a set of items is. While the admin menu
structure isn't 100% ideal (the top-level item is repeated also as a sub-item)
adding `aria-current="page"` to the sub-items gives an important feedback to
assistive technologies users.

This change introduces `aria-current` for the first time in core. Worth noting
there are other places where it can be used to improve accessibility. These should
be addressed in separate tickets and patches.

Andrea Fercia a4ae97437b Administration: Thickbox: Fix conflicts with the Plugin details and native Thickbox modals.
The Plugin details modal custom implementation in the Plugins page conflicts with
other Thickbox instances added by plugins. Thickbox shows its age and has been
modified over time to suit core needs. However, WordPress should do its best to
not create conflicts with the native Thickbox styles and functionalities. Plugin
authors should be able to use `add_thickbox()` in any admin page as documented, 
without having to worry about potential errors.

- fixes a JavaScript error when closing a native Thickbox modal in the Plugins page
- avoids to override the native Thickbox modal styles
- uses a CSS class to target the Plugin details modal and remove a pile of overqualified CSS selectors

Weston Ruter 9b5d71bad0 Widgets: Add dirty state tracking for widgets on admin screen.
* Mark a widget as dirty when a field input triggers a `change` or `input` event; clear dirty state when widget is successfully saved.
* Disable Save button and re-label "Saved" when widget not dirty.
* Show AYS dialog when leaving widgets admin screen with unsaved changes.
* When widgets are dirty, expand all unsaved widgets at AYS check and focus on first one.
* Change "Close" link to "Done"; hide link when widget is dirty and reveal when saved.
* The "Done" link persistently appears in the Customizer even after making a change (when the widget is dirty) because changes are autosaved into the changeset.
* Prevent saving widget when form fails `checkValidity`.
* Fix frequency of triggering of `change` event on the rich Text widget's `textarea` limited now to when there are actual changes.
* Add a class of `widget-dirty` to widget containers when the widget has unsaved changes.

iandunn 476377f64d Dashboard: Discontinue nonessential logging of Events API requests.
These log entries are only useful when troubleshooting unexpected results from the API, which is not common. The vast majority of users are better served by not having their logs cluttered with noise.

For the rare situations where troubleshooting is necessary, it can be achieved by a plugin (see #41217 for an example).

Props Howdy_McGee, dd32.

Joe McGill bbb8d48086 Media: Prime post caches in 'wp_make_content_images_responsive()'.
In [38296] we replaced `get_post_meta()` with `wp_get_attachment_metadata()`
so that attachment metadata could be consistently filtered. However, this
results in extra post queries which were previously avoided.

This uses `_prime_post_caches()` instead of `update_meta_cache()` to improve
post caching before looping through all images to retrieve attachment metadata.

Props dlh.
Fixes #40490.
