Summary: After navigating back and forth through the b/f cache, the web view is set to "copy on scroll" despite having content that should prohibit such behavior (e.g. fixed background). To reproduce: 1) Go to <http://www.w3.org/TR/CSS21/>. 2) Click on the "next" link. 3) Go back. 4) Go forward. 5) Scroll up and down. Expected result: The "W3 Working Draft" banner on the left to remain fixed and not scroll out of view. Actual result: The "W3 Working Draft" banner scrolls out of view when scrolling down, and artifacts appear when scrolling up. Regression: Yes, this doesn't happen in shipping Safari. Notes: While this is a rendering bug, it's ultimately caused by the page loading machinery not (re)setting up the view properly, so I'm filing under Page Loading.

Actually the regression in r13440 was fixed in r13649 (fix for bug 8079). It came back later.
