Test Case Reduction

Redraws for fixed backgrounds don't appear to be triggered automatically when applied to the same DOM node as a 3D CSS transform.

Steps to Reproduce:
1) Apply 3D CSS Transform to same node as a fixed-attachment background. (see attached test case for example)
2) Scroll down.
3) Force a redraw (partial or whole).  This can be done by (a) selecting text within the bounding box for a partial redraw or (b) resizing the window for a full redraw

Actual Results:
Visual tearing for partial redraws, and complete repositioning of background for full redraws.

Expected Results:
Background should behave as background-attachment: fixed, staying in one place while you scroll.

Mac OS 10.8.2, Chrome 24.0.1312.57
