This affects the `::walk()`, `::paged_walk()`, and `::get_number_of_root_elements()` methods.
PHP 8 changes the way string to number comparisons are performed: https://wiki.php.net/rfc/string_to_number_comparison
In particular, checking if an empty string is equal to zero in PHP 8 evaluates to `false`, not `true`.
For the `WP_Walker` class, this resulted in an incorrect handling of parent items in a few methods.
By explicitly checking for an `empty()` value instead, we make sure the check works as expected in PHP 8 and earlier versions.

When using the text widget, a `wp.editor.initialize is not a function` notice is encountered. This happens when `wp-editor` is loaded as a dependency, which assigns `wp.oldEditor = wp.editor` and then redefines `wp.editor`.
`wp-editor` is only used for the Classic block, which is not supported in the new widgets editor. [51198-51199] updated `@wordpress/block-library` to remove `wp-editor` as a dependency, but it’s still listed as a dependency of the `wp-block-directory` script handle.
Since the Block directory is not supported within the widgets editor, the related assets can safely be blocked from enqueueing.

This updates the widgets screen to load the editor styles in the same way as the post editor. This combined with the package updates in [51198] and [51199] ensures that the blocks added to sidebars more accurately reflect what will be displayed on the front end of the site.

Account for sites enabling Gutenberg as an mu-plugin when determining whether full-site-editing themes can be enabled. This replaces the check the plugin is active with a check whether the function `gutenberg_is_fse_theme()` is defined.

When a theme that uses the Full Site Editing feature is activated and the Gutenberg plugin is not present, the site will currently show a text notice on the front end. The user is not made aware of this unless they visit the front end of their site.
This adds a check that will prevent a theme from being activated when the `full-site-editing` tag is present in the theme’s `style.css` header and the Gutenberg plugin is not active to prevent this scenario.
These checks can be removed once Full Site Editing is completely merged into Core.

Restore inheriting the backbone fetch in the media library and adapt the AJAX response according to the action performed in the media query.
In [51145], the response shape was restored to the original shape, and a custom fetch was added to handle assigning the totalAttachments information in the collection. The custom fetch triggered a new set of bugs relating to zero-sized collections and loading individual images.

This switches to using Git in the local Docker environment install script to check out a copy of the WordPress Importer plugin for use in unit tests.
Previously, SVN was used and the commands were not correctly run within the Docker container. The container does not actually have SVN installed, and the script was only working when the machine running the command had SVN present.

After [51111], the `$post_ids` variable is now initialized as an empty array when processing a bulk action. As such, the original check using `isset` on `$post_ids` will always evaluate to `true`. This change swaps the `isset` checks for `empty` to check array length instead.
