    messageTray: Disable unredirection while showing banners
    
    We don't usually show notification banners while the monitor is in
    fullscreen, but when we do - the notification is urgent - we should
    actually show the banner, even if the top-most window is unredirected.
    To achieve that, disable unredirection while the banner is showing.
