Bug 1384435 - Don't clear animation only dirty bit during style recalc (unless the element is in a display:none subtree). r=birtles After bug 1356141, the setup of animation-only dirty bit should have matched to normal dirty bit's one (Though they don't match in post traversal due to throttled animation flush). An unset_animation_only_dirty_descendants call removed in this patch cleared dirty bits which are needed for post traversal if there is a second animation-only traversal and if there is no need to restyle for the second animation-only traversal. The reftest in this patch fails without either this fix or the fix for bug 1367975. See [Gecko bug 1384435 comment 12](https://bugzilla.mozilla.org/show_bug.cgi?id=1384435#c12) for more detail what's going on at that time.
