Title: Attach lazy retick to getComputedStyle after inline style change

Setting the inline style of an animated element causes the animation frame to completely re-evaluate so that getComputedStyle() can be accurate according to the new inline style and any animations ontop of it.

Users that set hundreds of inline styles per frame without calling getComputedStyle are punished with a useless animation tick after each set. This change fixes that.
