 Replying to [comment:27 westonruter]:
 > Since it is bundled with TinyMCE 4.x which is also an old release
 branch, and since there is an
 [https://github.com/WordPress/gutenberg/pull/50387 experiment] to stop
 loading TinyMCE by default in the block editor, it seems patching TinyMCE
 here isn't going to be critical.

 Right, also there aren't any plans to upgrade TinyMCE to a newer version
 (afaik). That would break all custom integrations (in core and third
 parties), as the new versions are not backwards compatible. Once TinyMCE
 is deprecated in the block editor, the only remaining place with
 significant use will be the old "Edit" screens that are enabled by the
 Classic Editor plugin.
