If a user scrolls to the bottom of the list, and then the list is then cleared and re-populated, the listbox will incorrectly display the listbox contents.

I created a simple test case here:

You populate a list, scroll to the bottom, clear it, and then re-populate it, and you will see incorrect results (both FireFox and IE9 do not have the problem - though they each handle the issue differently). Instead of the bottom of the list, the top of the list is displayed, even though the scroll bar indicates that you are at the bottom of the list.
