--- Comment #5 from Dean Jackson <dino at apple.com> ---
I don't think we need this change in AnimationBase::progress.

In that, we first calculate an overall running time that is the iteration count times the duration. If the elapsed time is above that, then we return 0 or 1 depending on the direction and which iteration it is.

So, even if (speaking in the terms of the function above) runningTime was 2, we'd immediately return 1.0 for progress. We never do the division to check loopCount.

Now, this fix might still make sense for the ports that use GraphicsLayerAnimation, but those people should review it.
