This page's style forces horizontal and vertical scrolling. Then, there's a script that uses document.documentElement.scrollTop and document.documentElement.scrollLeft to scroll 10px horizontally and vertically.
You can see that nothing happens. All other major browser get this right. This is a Webkit old error (see https://bugs.webkit.org/show_bug.cgi?id=9248). I hope you can go around it on Chrome.
