User Agent: Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/535.7 (KHTML, like Gecko) Chrome/16.0.912.77 Safari/535.7 Steps to reproduce: Applying a rectangular clip, then drawing content with shadowblur over the clipped rectangle. See attachment, click the "Clip" checkbox. Actual results: The clipped rectangle seems to be vertically offset by a value aprox twice the shadowOffsetY. Expected results: Clipped rectangle should respect shadow parameters. When no shadow is applied, clipping works fine.

This is a regression from FF8 (according to comment#1), and we have zero dupes, so I don't think this needs to be tracked for FF10 and up. Please nominate for Aurora/Beta approval if you disagree and feel there's ample reason to uplift.

I don't really mind either way, the only reason to uplift this might be that it's -extremely- low-risk.
