Subject: 28.0.50; ediff help frame does not display text
Date: Wed, 18 Aug 2021 14:39:39 -0400

I built emacs this morning from the git master branch.
The latest commit was 9b31ad36094666da6b3281025adc163829d89de8 with
a date stamp of Wed Aug 18 20:02:39 2021 +0300.
I am running the macos GUI version.
First I run /Applications/Emacs/Contents/MacOS/Emacs -Q
then I load two files and run 'ediff-buffers' to compare them.
ediff works just fine except that the frame with the help message
is an empty frame. The '?' command changes the frame size but the
text never renders.
