That's interesting.  Could you put a breakpoint on that C function on
GNU/Linux to see if it's called, for example, when you close the menu?
That may be the key difference between macOS and the other operating
systems.  I don't have a GNU/Linux system at hand right now, but I can
investigate if needed.

(BTW, as an aside, getting a Lisp backtrace using LLDB on macOS is a bit
time-consuming because of all the manual steps to print the pointer
structures.  If I have time, I'd like to write an .lldbinit file with
LLDB commands to make this process much simpler, although I don't know
how many people are debugging Emacs using LLDB here.)
