By the nature of antialiasing, the black fill used to cast the drop shadow is
showing through the antialiased clip that's supposed to cover it. There are
similar issues with solid borders, e.g.

<div style="width: 100px; height: 100px; -webkit-border-radius: 20px; border:
10px solid white; background: red;"></div>

I think some common cases involving solid backgrounds/borders can be fixed and
sped up. The cases reported here are more tricky because the background is
transparent.
