The js on this page is generating malformed html, which is not handled by webkit as nicely as FF or IE. In the js function createFaq(), they're opening a <div> and closing a </layer>. The <div>s don't get closed until the wrapping <ol> gets closed. The result is several nested <div>s, which then get overwritten when an faq is selected. Ideally, the <div>s without matching </div> would get closed before they ended up nesting (this appears to be how FF and IE are handling this page). (See http://code.google.com/p/chromium/issues/detail?id=8687 for original report)
