Virtualization support with ExpandStateMapping

1. When I start the application, only 5 items are displayed. My expectation all the parent note should be display

2. When I scroll down, nothing more displays until I scroll up, at that time, all the items are displayed, but again, when I scroll down, all items are disappear

3. The scrollbar display incorrectly, it displays as we have a very long list in Tree, but in fact, all items are collapse
