           Summary: Divs with overflow:auto: scrollbars not correctly
                    updated when contents change
           Product: WebKit
           Version: 523.x (Safari 3)
          Platform: Macintosh
        OS/Version: Mac OS X 10.5
            Status: UNCONFIRMED
          Severity: Normal
          Priority: P2
         Component: Layout and Rendering
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: khooyp at cs.umd.edu


I have a page set up with a overflow:auto div element. When the contents of the
div change (e.g. some children set to display:none), the scrollbar on the div
element doesn't seem to be updated correctly. If the user then clicks on the
scrollbar or attempts to scroll, the contents will jump to wherever the
scrollbar was incorrectly set to.

This doesn't seem to occur on the main scrollbars, just on elements with
overflow:auto set.

I'll attach a test page that shows this effect.
