Comment (by walterebert):

 Replying to [comment:4 desrosj]:
 > @walterebert could you test with WP 5.8 beta 3 to see if you can
 reproduce the issue with that release?

 I tried a fresh install and the issue was gone. Upgraded to WP 5.8 beta 4
 and everything works fine. Not sure what caused the problem, but I
 couldn't reproduce the problem so far.

 If will try some more things and report back.
