table cells get class="focus-visible"

[Metis77]

Description

Redactor sets class="focus-visible" to focuses tables inside redactor. If saving now, those classes stay at the table.

Steps to reproduce

1. add tablet to redacor entry
2. click a table column -> class="focus-visible" is added
3. save entry
4. BUG: class="focus-visible" stays

Maybe Solution: do not add class="focus-visible" on table cells inside redactor.

Additional info

• Craft version: 4.x
• PHP version: 8.1
• Plugins & versions: 3.0.2

I am seeing this issue as well in Craft 3.7.55.2:

Saving the entry actually saves the focus-visible class.

Still an issue with Craft 4.2.5.2 and Redactor 3.0.2. This is very annoying if you have styles for .focus-visible in the frontend as well, since you can't get rid of this without editing the HTML manually.

Workaround

Create a HTMLPurifier config inside config/htmlpurifier/something.json:

{
  "Attr.ForbiddenClasses": ["focus-visible"]
}

and enable this config for the Redactor field. After resaving the field, all focus-visible classes should have been removed.
