Title
Emacs Mac App Locks Up When Raising Context Menu
Description
I am able to intermittently lock up the Emacs Mac App when using context-menu mode (described in Menu Mouse Clicks (GNU Emacs Manual)).
Environment
OS: 14.1.1 (23B81) MacPorts: 2.8.1 HW: Apple M1 Pro
Steps to Reproduce
# Launch Emacs Mac App from command line using -Q argument to bypass any user configuration.
# Turn on context menu mode (M-x context-menu-mode)
# Repeatedly invoke/raise the context menu by right-mouse button (button 3) clicking on the current buffer and moving the mouse cursor over a menu item and pulling it away to not invoke a menu command.
Expected Result
No action should be taken by Emacs as no command from the context menu is selected.
Actual Result
Emacs Mac App locks up. The following message was emitted on the console:
┏━ cchoi@bingsu:/Applications/MacPorts/EmacsMac.app/Contents/MacOS
┗━━ $ ./Emacs.sh -Q

At this point, force quitting the app is the only available option, opening the risk to loss of state that is not persisted.
