Screenshot When HTML element is absolutely positioned, garbage can be shown outside HTML. What steps will reproduce the problem? 1. Open the attached abs-pos-html.html. (Any HTML document where HTML element is absolutely positioned should do.) 2. Resize the browser a few times. 3. Observe the area outside of HTML, i.e., outside the red box. What is the expected output? What do you see instead? The page should be rendered cleanly. Instead, the area outside the red box contains garbages, e.g., gray lines. Please see the attached screenshot. Firefox 3.6 and Opera 10.10 draws cleanly on OS X 10.5.8 and Vista SP1. IE8 puts HTML at (0, 0), i.e., ignores the position property. Both WebKit 455974 and Chrome 5.0.307.11 beta fail.
