Summary Iframe overlap testing fails to detect overlapping objects in the same layer

Iframes use the OverlapTestRequest mechanism to detect when they are overlapped and disable copy-on-scroll in that case. The mechanism detects overlapping layers, but fails to detect overlapping objects in the same layer as the iframe. The attached test case demonstrates the bug.
