I got a chance to check this under Emacs 28, and the bug exists there 
too, so it'd be nice to backport.

Ok, here's a patch to do it. There might be a better way to do this, but 
it should work reliably.

Note: this patch doesn't fix the duplicated separators in the help-mode 
context menu. I haven't had time to look into the right way to fix that 
yet (there may be other mode-specific context menu functions that have 
this bug too).
