To reproduce: 1. Go to http://us.battle.net/wow/en/game/dungeon-helper/ The Flash plugin on the right side of the page has a black background. It should instead have a transparent background (due to wmode=transparent). This bug does not occur in WebKit1.

I am having a surprisingly hard time writing a test case for this. I can't get transparent plugins to show up at all.

I'm going to land this without a test case. I filed bug 60169 to cover writing a test.
