Description Charles Ying 2009-03-09 17:56:47 PDT 
1. Load the URL and mouse over the screenshot.
2. Notice a clipped box shadow on the scaled up image.
3. Mouse out, notice a trail of repaint bugs as the image scales back down.

Testcase

For the bug to happen:
* The transitioning element has to be a replaced element
* The transform has to have a translate in it
