Attachment: testcase

When a transparent gif is nested inside an anchor and the CSS a.hover is set to
change the background, the background isn't changed correctly "behind" the
transparent gif.

The background of the <a> is changing.  The background of the <img> is not
changing, nor should it -- it has no background set anywhere.

The <a> is not as tall as the image in this case, and that is correct -- the
<img> should not be affecting the line height.
