Opacity transition test with AC

With AC enabled, opacity transitions first seem to work fine but after the transition is finished, the element is rendered again with the old opacity that was the starting point in the transition. Without AC the element's opacity correctly sticks with the new opacity value after transition.

Attached a test case to demonstrate the issue.
