When it comes to keybindings or gestures, there's not really a good reason why popups associated with the top bar should behave differently from any other shell menus. Just set the action mode generically for all menus, so actions like screenshots or media-keys start working with menus like the background- or app launcher context menus. https://bugzilla.gnome.org/show_bug.cgi?id=745039
