Hi,

it seems that this bug is so apparent that Apple's own guidelines have to workaround it, as they're all using setTimeout to restart an animation. This is actually pretty severe, as there's currently no way to animate smoothly from one keyframe based animation to another.

I'm having this specific issue as I'm animating walking characters in an isometric path (in eight directions). So the animation goes into one direction for one tile (say, 45px), and then the animation needs to be restarted due to the nature of the tiling. With setTimeout and plenty of characters, you'll see noticable pauses, as the setTimeout is only executed after the current action queue is done.

If there's already another workaround for this, please let me know and I'll be quiet :)
