Testcase based on python-xlib

This also happens with my volume knob on LXDE powered by Audacious Media Player and my keybindings (the ones which don't create or show new windows) powered by xbindkeys.

It seems that the problem is Firefox killing Fullscreen mode for videos on detection of any input event not directed to it. (In this case, keypresses reserved by XGrabKey)

I don't have time to determine how Firefox actually decides what a noteworthy event is, but I've attached a testcase based on python-xlib which demonstrates the issue using the keybinding Ctrl+Super+Spacebar.
