Sample URL pulled from blog comments. If the rotating graphic is selected, a selection highlight "smears" around the edges as it rotates.

The bug only happens when replaced content is rotated -- see new attached test-case.

Thanks for the testcase; it reproduced in TOT. It actually looks like the selection rendering for the replaced element is wrong as soon as the replace element gets a transform. Testcase coming.
