The frame remains full screen, both when immediately when I make the
change and also when I choose "revert".   When I selected "revert" it
did drop briefly out of full-screen mode but then restored itself
properly immediately thereafter.  I have several displays and most of
them have a full-screen emacs in them most of the time.  LMK if there
else I could assist with.  Emacs 27.1 GNU bin dist.
