I see Transform, but not WebKitTransform here, is that intentional?

Yes, in the animation system we only want to animate one of these at a time. So
both are mapped to CSSPropertyTransform internally.

             || activeAnimations->hasActiveAnimations(CSSPropertyWebkitFilter))
             return true;
     }
