Comment:

 @conner_bw thanks for your report! As you may know, TinyMCE is an external
 library and there's not so much WordPress can do to directly change its
 code. I see the issue has been already reported upstream, so I'd lean
 towards closing this ticket.

 That said, this is a border-line case and very close to WAVE reporting
 false positives. While the markup used by TinyMCE for the toolbar buttons
 is a bit unusual, I'd argue WAVE doesn't understand the necessary
 semantics and labelling are rebuilt with ARIA roles and attributes on the
 `<div>`s that wrap the buttons. This particular markup may not be 100%
 compliant (technically, `role="presentation"` is not allowed on button
 elements) but it works in the real world.

 Worth considering all the automated "accessibility checkers" always
 require manual checking. They help a lot in identifying the most common
 violations but sometimes they just can't understand what's going on.

 As far as I can tell, all the TinyMCE buttons are announced properly and
 are operable with keyboard and screen readers. The only exception is the
 "Text color" button: this is a known issue, see for example
 ticket:35710#comment:30 and hopefully will be fixed in the next TinyMCE
 versions.
