Jason, I think you forgot to attach the testcase.

Attachment: test case

in this test case, the background visible in the browser window is white, until you scroll to the right where it reverts to black.  it should be white irrespective of how far to the right you scroll.

Safari's behaviour is very similar

I can confirm the effect and it's clear why this isn't the desired behaviour.

I think the rendering is technically correct, though. The div element in testcase2 takes the available width (width of the body). The content rendered outside is simply overflow.

I'd say the bug is invalid, but I'm adding roc for another opinion.
