    padOsd: Apply specific CSS to Button/Leader SVG classes
    
    Applying a fill operation on the Leader line path seems to close
    it, resulting in filled polygon. Bug or not this is not the intended
    result here, we can do less ambiguously by not specifying the fill
    CSS property to the Leader class.
