This is another piece of native OS UI, so I'm not sure what we can do about this other than writing a custom app menu.

If we make this menu accessible through a keyboard shortcut, such as "Alt + F" for File menu, would that be an acceptable solution or does it have to be accessible via "Tab" focus?

Verified in latest bot emulator Version 4.5.2-78154 by using
I have verified with "Alt+F" key still File menu is not accessible and better to provide tab focus also for keyboard dependent users will help a lot .
