List scrolling in sheet
List scrolling in a sheet combined with a tabbed interface seems to be broken on initial load using PR3. The list is initially empty and hidden but within the default tab. When the list is populated and shown it is unscrollable. In order the get scrolling to work users must switch tabs while the list is open. I assume doing so forces a recalc of the list size. See http://18.104.22.168/parking/website/ for use case.
Can I get a simple test case provided here?
