    Don't allow border-radius in headerbars when using server-side decorations
    
    The Ambiance theme isn't smart enough to give headerbars square corners
    when they aren't being used as title bars.  In this case, they're always
    inside vertical Gtk.Boxes, so we target a CSS rule at that.
