Accordion doLayout is resetting the page scroll position

Ext version tested:

• Ext 4.2.2

Browser versions tested against:

• IE8


• IE9


• FF 22.0


• Chrome 33.0

Description:

• Given an accordion layout that is longer than the screen, when I scroll down and expand or collapse a panel the scroll position on the page is lost. The scroll position jumps to the top of the accordion panel.

Steps to reproduce the problem:

• See this jsfiddle: http://ift.tt/PLC9ne

The result that was expected:

• The scroll position should be maintained

The result that occurs instead:

• The scroll bar jumps to the top of the accordion

The only workaround I have found for this is to store the current scroll position in the beforeexpand and beforecollapse handlers for each panel in the accordion. And on the accordion itself call window.scrollTo(0, storedScrollPos) in the afterlayout handler.
