    overview: Use whole stage size for cover pane
    
    We show a cover pane on top of the overview during transitions to
    prevent issues caused by clicks and mouseover events when the overview
    is not ready. Right now, this pane is only being shown on the primary
    monitor, which obviosly allows interactions to happen before the
    animations are finished on the secondary monitors.
    
    To fix this, use the size of the whole stage for the cover pane.
