Attachment: Test case (click on iframe scrollbar)

This is the test case (first link in comment 0). I can repro on OS X in 57 beta as well.

(Well what I'm seeing on OS X is the scroll thumb gets truncated. The top half is gone but the bottom half is still drawn. Happens on any scrolling or clicking in the iframe).
