Summary Animations breaking stacking context of generated content

When animating a node that has z-indexed generated content and applying a transformation, the stacking context is lost (perhaps the node is receiving a z-index during the transformation?), and the node is positioned between the generated content and the canvas, instead of the generated content remaining behind the node. See http://jsfiddle.net/q7Qh5/15/

This does seem to be specifically an issue with pseudoelements: see http://jsfiddle.net/xhWMc/ for the same example using real divs - z-index is maintained.

All browsers seem to have this behavior.
