    wayland: Ensure to set gtk_surface dbus properties after hide()
    
    Currently hiding destroys the wl_surface and all related interfaces,
    (including the gtk_surface1) so the next time the GdkWindow is mapped,
    we don't bother to set the DBus properties. Toggle the check off so
    it's actually issued again after the GdkWindow gets a gtk_surface1.
