Visual while scrolling the page

The following test case can describe the bug most accurately:

https://gist.github.com/mponizil/8483445

Notes:

(1) Body is scrollable
(2) Document includes an element that makes use of a -webkit-animation
(3) Top-level div has z-index defined (accompanied by some position declaration)
(4) Next-level div is position: fixed
(5) Next-level div provides scrolling with overflow-y: auto
(6) Children of scrolling div include position: relative

The bug goes away if any of the elements descending from the top-level div have -webkit-transform:translate3d(0,0,0)

Thanks!
