Bug 1245075 patch 2 - Fix EffectSet::GetEffectSet(nsIFrame*) and EffectCompositor::GetAnimationElementAndPseudoForFrame to only return effects when the frame is the style frame for its content. r=birtles This means that we won't associate animations with additional frames. In this case, this fixes associating off-main-thread animations with a table outer frame, when they should have been associated only with the table frame. Locally, the test fails without the patch (with opacity in the test being 0.36 instead of the expected 0.6), and passes with the patch. (Opacity 0.36 gives a color of rgb(163,163,255), whereas 0.6 gives rgb(102,102,255).) --HG-- extra : commitid : 7wtkIDLDHBF 2016-02-07 16:43:49 +00:00			`<!DOCTYPE html>`
