Created attachment 259025 [details] try to scroll the content inside the red box. A simple example can repro this issue: <body> <div id="#red" style="position: fixed; width: 200px; height: 200px; top: 0px; left: 0; background-color:red; overflow-y: auto;"> <div style="height: 3000px; width: 10px; background: green; margin: 10px;"></div> </div> </body> the scrollbar in #red doesn't render anymore, but if I change its position to absolute, then the scrollbar is back.

One more bug. If the document scrollTop > 0, then you can't scroll the content inside the red container anymore. It works fine in Chrome and Firefox.

This seems to work correctly in a WebKit nightly.
