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.

So the problem is really with scrolling back, confirmed! Good testcase, allthough it's probably hard to automate this one.
