Hiroyuki Ikezoe 72ab9ce7e5 Bug 1278136 - Part 2: We should not check whether the animation can run on the compositor or it's paused when determining if we should create a stacking context. r=birtles,mattwoodrow ...

We should create a stacking context for any transform or opacity animations
that are either "in effect" (what we currently do) OR "current", i.e.
scheduled to run or running. *BUT* for now, we don't create any stacking
context in before phase without fill:backwards or fill:both because the
property never wins in cascade until the animation gets "in effect".  This
restriction will be removed in a subsequent patch in this bug after landing
bug 1279403.
