I had a strange issue when running an animation the first time after every page load. I was animating the scaling and left/top properties of an element (using the same .animate call). The element would end up in the right place, but moved there in a curve instead of along a straight line.
This would happen consistently on the first run after refreshing the page. I noticed the element would be left with an extra attribute after the first run, like:
data-transform="origin(0px, 0px) scale(1, 1)"
Adding that in the HTML fixed the problem.
I was not able to reproduce the problem in a small example for now.
