    layout: Keep the top_window group above newly added chrome
    
    The top_window_group was introduced for popup windows that should
    appear above system chrome, but as the group itself is just a child
    of Main.uiGroup, chrome that is added after top_window_group will
    still be stacked on top.
    At least correct the stacking for actors added via addChrome().
