Bug 1278136 - Part 5: Create a stacking context for opacity/transform animations even if it's in delay phase and even if the property is overridden by !important rules. r=birtles This patch introduces a new functions named HasEffectiveAnimationOfProperty. This function checks that a given CSS property is overridden by !important rules. On the other hand, now KeyframeEffetReadOnly::HasAnimationOfProperty() does just check that the effect has a given CSS property. This is used to create a stacking context because we should create a stacking context for opacity or transform animations even if the property is overridden by !important rules.
