You won't be able to see this on any system but MS-Windows. On
Windows, the Emacs menus are implemented in a way that has this
unfortunate side effect: we basically preempt the Emacs command loop
for as long as the menu stays open.
If someone wants to redesign how Emacs menus are implemented on
Windows, I think that would be very welcome. But until that happens,
this is Emacs "functioning as designed", not some easily-fixed bug.
