    keyboard: Ignore focus changes caused by tray showing/hiding
    
    The keyboard is shown/hidden automatically when (un)focusing a
    ClutterText actor. This behavior breaks with the message tray now
    grabbing/releasing key focus when toggled. Fix this by ignoring
    all focus changes to or from the message tray.
