Just as with c35b4cede58142797b1f6b04a4e2e7eaa938234a, there's no default vfunc implemented by any parent which causes gjs to crash when trying to call it. So return EVENT_STOP if the key press successfully toggled the button, and EVENT_PROPAGATE otherwise. https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/830
