We don't currently have a mechanism for rerendering when the front/back flips, so we should disable running such animations on the compositor thread for now until we do. Bug 1186204 covers reenabling. The reftest fails without the patch (showing a blue almost-square rectangle), and passes with the patch. The use of reftest-no-flush (added in patch 1) is needed to achieve the failure without the patch, because the flushWindow() function in reftest-content.js calls getBoundingClientRect() to flush rendering, which has the side-effect of flushing style updates that have been suppressed on the main thread while we're running an animation off the main thread, which in turn covers up the bug. --HG-- rename : layout/reftests/transform-3d/animate-preserve3d-child.html => layout/reftests/transform-3d/animate-backface-hidden.html
