This is the test case.  It works correctly in the latest Safari and Opera releases (all canvases are green).

Fixed some silly problems with HTML structure, and not properly filling the fourth canvas with the initial red color.

Yeah, this was apparently a spec change...

FWIW, the WIP patch in bug 498826 fixes this issue.

Test case v3 is passing at my end (with both Firefox 7.0.1 and with nightly build on Linux). I guess this issue is fixed now.

I also confirmed Test case v3 is all green.
Resolving per comment #5 and #6.
