    Adwaita: Propagate bg color to titlebar separator descendants
    
    Gives the same background color to all separators descending from a
    title bar than to its direct childrens.
    
    This prevents separators which are in a titlebar but not direct children
    from the widget with the titlebar style class from being almost
    transparent and hence it prevent them from revealing the clear color of
    the window's titlebar (black).
