    layout: Use addChrome instead of addTopChrome for screenShieldGroup
    
    Make sure the panel is visible above the login and screen shield actors
    by adding the screenShieldGroup to the uiGroup underneath the panelBox.
    
    This fixes a regression introduced with 2bd80579eddba9804871ce6c8de742bdf9b1d800
