    Fix titlebar visibility with virtual monitors
    
    Virtual monitors and monitors are now a single page, so checking
    the popcount is not enough - it'll return 2 if VIRTUAL | MONITOR
    was passed, but in fact only a single page is visible.
    
    Fix that by checking if a WINDOW type is passed to, which will
    in fact cause two pages of the stack to be visible.
