#60372: This update broke functions

 I use Classic Editor. Certain things stopped working as soon as I updated
 to 6.4.2. The text tab won't open so I can't customize or fix formatting
 in posts using html. (It's visible, but nothing happens when clicked on.)
 Same for "Screen Options" and "Help". They are visible but don't work. The
 menu options on the left are in the truncated column with just icons
 showing - clicking the expand icon doesn't work.

 I tried logging out and back in, that didn't help.

 The only plug-in I have that doesn't show it is tested as compatible with
 this version of WordPress is WordPress Editorial Calendar. I can't imagine
 that would be related to this issue. So I don't know why I'm having
 problems.
