    Avoid invariant checking spew in gnome-shell
    
    For normal toplevels, visible is tightly bound to mapped, but for
    something like a toplevel that exists within a Clutter stage we
    may want to make mapping dependenton external factors, so we shouldn't
    actually checked that !mapped toplevels are !visible.
