Hmpf, despite above when trying mozregression --repo=mozilla-inbound --good=2011-12-20 --bad=2012-01-31 --args="http://edition.cnn.com/2012/12/27/opinion/ghitis-2013-social-change/index.html?hpt=hp_c1" against Flash 11.6.602.108 all Builds are WFM - weird.... Alice? :-)

Thanks Alice. Looking through the dependency tree for that bug, i found that this is apparently a duplicate of bug 784131 (when clicking "close" on the video, the element wrapping the flash element goes display:none).
