A couple of notes on the test case:
- This test only fails intermittently on trunk. If you load the attached HTML file, you'll see that it occasionally renders correctly (both squares green), but most of the time you'll see that the bottom-right square is red. It always works correctly with the patch applied.
- I have another test that more directly models the bug, by changing a child of the <g> element, which causes the rest of the cached ImageBuffer to get blown away (as in the bug description). But for the life of me I can't get it to fail when running in test_shell or as a layout test. I believe this has something to do with differences between the painting logic in test_shell and chrome/safari.
