This change fixes 2 issues:
1 The focus lock for modals (e.g. within Tiny editor) did not
correctly loop round from the end of the modal to the start.
2 After clicking 'Browse repositories' button in a Tiny editor
modal, and closing the file picker, focus did not return to
the button as expected.
This was introduced in Tiny 7.1 to focus notifications, but it conflicts
with the German keyboard layout which uses Alt+F12 to access the open
curly brace.
This is an upstream problem with TinyMCE and should be fixed in a future
release.
The recommended workaround is to disable the shortcut.

The quickbars selection toolbar is not displayed correctly
if the target element is too small. We will wait for it
to be fixed in the future before we re-enable it in Moodle
The TinyMCE.remove() function is killing other events on Firefox
We need to modify the setupForElementId() to make TinyMCE to
remove itself outside of the event loop
Since version 6.4 and later, TinyMCE had a feature `ui_mode: split`.
It enables support for editors in scrollable containers,
and Moodle has some pages, especially the course pages, that are using the scrollable containers.
Therefore, all workaround that is addressed should be replaced by the feature to avoid future problems
regarding the overflow and the z-index issues.
TinyMCE has a default entity_encoding 'named',
which causes text with diacritic symbols to be converted to HTML entities,
e.g. pâté will be convert to pâté
That will be a problem with the Glossary auto-linking filter if a course has a text concept like pâté,
then the filter will likely fail to get the text concept.
Changing the TinyMCE entity_encoding to 'raw' will resolve the problem.
This is in keeping with other Editors such as Atto and resolves an issue
where DOM Purification incorrectly identifies HTML-like string content
as an HTML tag with a JS variable.
Moodle already performs XSS sanitisation using HTML Purifier in PHP.
The boost theme makes the TinyMCE editor rendered in a scrollable container,
scrolling the editor’s container will cause TinyMCE UI elements to be detached from the anchor.
Therefore, to keep the tinyMCE menu in the correct position,
adjustments must be made on the page drawers style.
When using TinyMCE editor in Safari browsers, a problem may occur where the dialogue
windows (such as modal dialogs) overlap with page drawers due to a specific behavior
in Safari's rendering. This function addresses the issue by adjusting the CSS overflow
property of the page drawers, ensuring they do not obscure the dialogue windows.
