* Edits to active plugins which cause PHP fatal errors will no longer auto-deactivate the plugin. Supersedes #39766.
* Introduce sandboxed PHP file edits for active themes, preventing accidental whitescreening of a user's site when introducing a fatal error.
* After writing a change to a PHP file for an active theme or plugin, perform loopback requests on the file editor admin screens and the homepage to check for fatal errors. If a fatal error is encountered, roll back the edited file and display the error to the user to fix and try again.
* Introduce a secure way to scrape PHP fatal errors from a site via `wp_start_scraping_edited_file_errors()` and `wp_finalize_scraping_edited_file_errors()`.
* Moves file modifications from `theme-editor.php` and `plugin-editor.php` to common `wp_edit_theme_plugin_file()` function.
* Refactor themes and plugin editors to submit file changes via Ajax instead of doing full page refreshes when JS is available.
* Use `get` method for theme/plugin dropdowns.
* Improve styling of plugin editors, including width of plugin/theme dropdowns.
* Improve notices API for theme/plugin editor JS component.
* Strip common base directory from plugin file list. See #24048.

Unify the theme-browsing and theme-customization experiences by introducing a comprehensive theme browser and installer directly accessible in the customizer. Replaces the customizer theme switcher with a full-screen panel for discovering/browsing and installing themes available on WordPress.org. Themes can now be installed and previewed directly in the customizer without entering the wp-admin context. Also includes an extensible framework for browsing and installing themes from other sources.
Also includes CSS auto-prefixing added via `grunt precommit:css`.

* Adds a new Publish Settings section for managing the changeset status, scheduled date, and frontend preview link.
* Updates Publish button to reflect the status selected in the Publish Settings (including Save Draft and Schedule).
* Deactivates the Themes section when a non-publish status selected, and deactivates the Publish Settings section when previewing a theme switch.
* Introduces an `outer` section type (`wp.customize.OuterSection` in JS) for the Publish Settings section to use and for available widgets and available nav menu panels to use in the future. These sections can be expanded while other sections are expanded.
* Introduces `WP_Customize_Date_Time_Control` in PHP and `wp.customize.DateTimeControl` in JS for managing a date/time value.

* Auto-publishes a scheduled changeset when attempting to access one that missed its schedule.

class used in the admin can be updated to use modern CSS and correct syntax. See
https://github.com/wpaccessibility/a11ythemepatterns/blob/master/read-more-links/style.css
Worth noting the `clip` property is deprecated and kept for IE11 and Edge.
- uses `clip-path` for modern browsers
- keeps `clip` for old browsers and update its value to a correct syntax
- resets `clip-path` to `none` where the class is used to dynamically reveal elements

Calling the `count_users()` function is expensive, regardless of the counting strategy that's used, and it gets
slower the more users there are on a site. In order to speed up the Users screen in the admin area, calling
`count_users()` can be avoided entirely while still displaying the total count for users.
This introduces some new functions:
* `wp_is_large_user_count()`
* `wp_get_active_user_count()`
* `wp_update_active_user_count()`

* Autosaved changes made on top of `auto-draft` changesets get written on top of the `auto-draft` itself, similar to how autosaves for posts will overwrite post drafts.
* Autosaved changes made to saved changesets (e.g. `draft`, `future`) will be placed into an autosave revision for that changeset and that user.
* Opening the Customizer will now prompt the user to restore their most recent auto-draft changeset; if notification is dismissed or ignored then the auto-draft will be marked as dismissed and will not be prompted to user in a notification again.
* Customizer will no longer automatically supply the `changeset_uuid` param in the `customize.php` URL when branching changesets are not active.
* If user closes Customizer explicitly via clicking on X link, then autosave auto-draft/autosave will be dismissed so as to not be prompted again.
* If there is a changeset already saved as a `draft` or `future` (UI is forthcoming) then this changeset will now be autoloaded for the user to keep making additional changes. This is the linear model for changesets.
* To restore the previous behavior of the Customizer where each session started a new changeset, regardless of whether or not there was an existing changeset saved, there is now a `customize_changeset_branching` hook which can be filtered to return `true`.
* `wp.customize.requestChangesetUpdate()` now supports a second with options including `autosave`, `title`, and `date`.
* The window `blur` event for `customize.php` has been replaced with a `visibilitychange` event to reduce autosave requests when clicking into preview window.
* Adds `autosaved` and `branching` args to `WP_Customize_Manager`.
* The `changeset_uuid` param for `WP_Customize_Manager` is extended to recognize a `false` value which causes the Customizer to defer identifying the UUID until `after_setup_theme` in the new `WP_Customize_Manager::establish_loaded_changeset()` method.
* A new `customize_autosaved` query parameter can now be supplied which is passed into the `autosaved` arg in `WP_Customize_Manager`; this option is an opt-in to source data from the autosave revision, allowing a user to restore autosaved changes.

* The CodeMirror component in the Custom HTML widget is integrated in a similar way to TinyMCE being integrated into the Text widget, adopting the same approach for integrating dynamic JavaScript-initialized fields.
* Linting is performed for JS, CSS, HTML, and JSON via JSHint, CSSLint, HTMLHint, and JSONLint respectively. Linting is not yet supported for PHP.
* When user lacks `unfiltered_html` the capability, the Custom HTML widget will report any Kses-invalid elements and attributes as errors via a custom Kses rule for HTMLHint.
* When linting errors are detected, the user will be prevented from saving the code until the errors are fixed, reducing instances of broken websites.
* The placeholder value is removed from Custom CSS in favor of a fleshed-out section description which now auto-expands when the CSS field is empty. See #39892.

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.
