To fix the dynamic properties, the following changes are included:
* Removes `WP_Admin_Bar::__get()`.
* Declares `menu` as a property on the class, deprecates it, and initializes it to an empty array.
* Removes the unused 'proto' dynamic property.
Dynamic (non-explicitly declared) properties are deprecated as of PHP 8.2 and are expected to become a fatal error in PHP 9.0.
== Why remove the `WP_Admin_Bar::__get()` magic method?
tl;dr
The magic method is no longer needed.
The magic method only handled the `menu` and `proto` dynamic properties. Introducing a full set of magic methods is overkill for this class. Instead of having to maintain magic methods, this changeset instead directly addresses the 2 properties (see below).
== Why declare the `menu` property on the class?
tl;dr
To simplify the code while maintaining backwards compatibility for extenders who are using this deprecated property.
The `menu` property was introduced during the 3.1.0 ''development cycle'' as a declared property [15671]. Its purpose was to ''internally'' hold the menu structure.
During the WP 3.3.0 development cycle, it was replaced by a new `private` property called `nodes` (see [19120]).
But breakage reports from extenders caused it to be restored. [19501] added the `__get()` magic method, i.e. for handling it as a dynamic property, and deprecated it.
>We're not going to maintain compat for $menu. Suggest we make it array() and plugins will have to deal. We can throw a _deprecated_argument() and push them to use the new methods.

[https://wpdirectory.net/search/01GSTW1X69TBN8FH3SY7V8KPY5 A search of the wp.org plugins and themes repository] shows that a few plugins are still using this deprecated property. To maintain backwards compatibility, `menu` is moved back to the class as a declared property, set to an empty array (as it's been since 3.3.0), and deprecated in the property's description.
== Why remove the `proto` dynamic property?
tl;dr
* It was not intended to be released in 3.1.
* There are no usages of it in Core or in the WP.org's plugin or theme directories.
* It should be safe to remove.
This property was first introduced in the WP 3.1.0 ''development cycle'' to replace the `PROTO` constant (see [16038]) for protocol handling for the admin bar's hyperlinks. [16077] replaced the property's usages with URL functions such as `get_admin_url()` and `admin_url()`. But it missed removing the property, which was no longer needed or used.
It was relocated to the `__get()` magic method as a dynamic property when the `menu` property was restored (see [19501]).
A search of WP.org's plugins and themes repositories shows no usages of the property. Core hasn't used it since the removed in [16038] before 3.1 final release. It should be safe to remove it, but committing very early in the 6.3 alpha cycle to give time for reports of usages, if there are any.

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 links is unnecessary there, as the toolbar is the first thing in the DOM within the `<body>` element.
For themes that don't implement the `wp_body_open` action yet and render the admin bar in the footer, the "Skip to toolbar" link with `tabindex="1"` is still necessary, to ensure it's the first focusable element in the page.

In WordPress 3.2 support for IE6 was dropped, IE7 followed a few versions later. With the 4.8 release, WordPress officially ended support for Internet Explorer versions 8, 9, and 10. Yet, we still have shipped CSS for the unsupported IE versions....until now! Goodbye to ie.css and star hacks!
* Removes ie.css and `ie` style handle.
* Removes IE specific class names and any related CSS.
* Drops support for IE8 and older in `wp_customize_support_script()`.
* Updates compatibility mode for CSS minification to `ie11`.

This is only a wrapper for the `add_node()` method, but it's in widespread use both in core until [46642] and in thousands of plugins and themes. Deprecating it would have made sense when #19647 was originally opened but that's no longer the case.

Using the new fatal handler introduced in [44962], an email is sent to the admin when a fatal error occurs. This email includes a secret link to enter recovery mode. When clicked, the link will be validated and on success a cookie will be placed on the client, enabling recovery mode for that user. This functionality is executed early before plugins and themes are loaded, in order to be unaffected by potential fatal errors these might be causing.
When in recovery mode, broken plugins and themes will be paused for that client, so that they are able to access the admin backend despite of these errors. They are notified about the broken extensions and the errors caused, and can then decide whether they would like to temporarily deactivate the extension or fix the problem and resume the extension.
A link in the admin bar allows the client to exit recovery mode.

CSS generated content is rendered for speech output. When it's not meant to be announced by assistive technologies, for example with font icons, special care should be used to hide it. At the moment, the only reliable way to do this is making use of a wrapper element and set `aria-hidden="true"` on it.

When Internet Explorer encounters a non interactive element with a `tabindex`
attribute, it adds the element to the accessibility tree with a `role=group` and
an accessible name computed from the element. This prevents JAWS from announcing
any fieldset legend within the element.
- removes `tabindex="0"` from the content and the toolbar containers: these tabindex attributes are no longer needed
- removes `aria-label="Main content"` from the content container: not needed
- keeps the media modal focus fallback introduced in [38142] by making the `#wpbody-content` element focusable only when needed

The admin bar render methods use some cute tricks which don't come close to the WordPress coding standards. So that we can more easily apply automated code fixing to the codebase, these tricks need to be removed.

Prior to about 2013, many class methods lacked even access modifiers which made the `@access` notations that much more useful. Now that we've gotten to a point where the codebase is more mature from a maintenance perspective and we can finally remove these notations. Notable exceptions to this change include standalone functions notated as private as well as some classes still considered to represent "private" APIs.

CSS generated content is going to be rendered for speech output more and more in
the next future. When it's not intended to be available for speech output, for
example with font icons, then special care should be used to hide it from
assistive technologies. At the moment, the only reliable way to do this is making
use of a wrapper element and set `aria-hidden="true"` on it.

* Makes the admin fully responsive down to 320px wide.
* Adds a touch-optimized main menu that can be opened and closed from the toolbar.
* Size and positioning adjustments to icons, buttons, and text elements for better touch usability.
A few changes since MP6:
* Removed jQuery mobile. This script was used to add swipe controls to open/close the sidebar menu. This feature was apparently buggy and due to the pending demise of jQuery mobile, it was removed.
* Removed use of Backbone.js. Adding Backbone.js to this script would add a dependency of Backbone.js for all of the admin. Additionally, it was used to add a menu item. Instead of doing that, it was added via the admin menu API. This also fixes a bad delay in the item showing in the menu.
* CSS layout is standardized. Comments have also been cleaned up.
* Jetpack and Akismet code is removed.
* RTL CSS is removed.
* JS passes hinting other than one small issue that will likely be removed when parts of the code are reviewed.
A number of areas for improvement remain; we're tracking these issues in the comments of #25858.
