How do you force a XUL tree to scroll in code?

I have an app written in XUL which contains a custom tree view that has many items. I've got a button that allows the selected item to be removed but my problem is that whenever this button is pressed, the tree gets scrolled all the way to the top. I have tried to fix this by re-selecting the item at the old index, but unfortunately this does not scroll the view. Is there a way I can get the tree view to either not scroll to the top or force it to re-scroll back to the original position? My code looks something like this: onRemoveNilSelection: function(event) { var selectedIndex = this._tree.currentIndex; this._treeView.removeItem(selectedIndex); this._tree.view = this._treeView; this._treeView.selection.select(selectedIndex); },
