servo: Merge #19617 - style: Fix inheritance of animation and transition properties of mismatched length (from emilio:inherit-animation-stuff); r=hiro At least when the animation-name length is bigger than the animation properties, we mess up inheritance and only set properly the specified counts, then don't cycle it. The nicer fix for this is making these vectors properly, and move the cycling logic at used-value time (bug 1420928). Same for transitions.
