           Summary: Focused element doesn't scroll into view properly if
                    inside two levels of "position : absolute"
           Product: WebKit
           Version: 420+ (nightly)
          Platform: Macintosh
        OS/Version: Mac OS X 10.4
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: New Bugs

Place some focusable elements, such as text fields, inside a scrollable element
(such as <div style="overflow : auto;">). If you tab into or otherwise focus an
element that falls outside the visible area, the element will scroll into view.

However, sometimes it is possible for the focused element to remaing outside
the visible area. This happends if the focused element is inside an absolutely
positioned, scrollable element (such as <div style="position : absolute;
overflow : auto;">) and that element inside an another absolutely positioned
element (again, <div style="position : absolute;">). The scrollable container
will scroll down before necessary and will not scroll up until too late.

See the attached testcase for demostration. Tested in nightly r15500 and 2.0.4.
