bug#44167: 28.0.50; Menu Misbehavior

[Rustom Mody]

I followed the recipe in this doc:
https://www.gnu.org/software/emacs/manual/html_node/elisp/Menu-Bar.html#Menu-Bar

ie
Put that code consisting of 3 define-keys in a file and loaded it
Emacs started as "-Q"

The menu does not work
(Actually the first couple of clicks show no response; then only the
darker background of menu WITHOUT TEXT)
See attached screenshot
The screenshot is not very accurate: its black in emacs but when the
screenshot key is pressed it begins to disappear.
Evidently the capture happens as its fading out
But its clear that there is NO TEXT IN MENU

After F10 it works
ie the words menu opens and shows

Backward-word M-b
Forward-word M-f

This is on 28.0.50
But its same on 27.1 also
