You don't need to animate to see this.

Shadows don't respect transforms, but the bounding box computations are unaware of this. Arguably, transforming a box should transform its shadow, but I can also imagine arguments to the contrary.

See also bug 22159, on focus ring smears.

Ha, this works fine now. Probably fixed via bug 19623
Comment 5 mitz 2008-11-20 21:14:46 PST
Actually I think it was fixed by making shadows respect transforms to the extent that they can in <http://trac.webkit.org/changeset/34377>.
