Listbox virtualized with zoom in/out (using LayoutTransformControl) issues

[Whiletru3]

Describe the bug

If we use a ListBox with a LayoutTransformControl in the ListBoxItem to be able to zoom in/out, there are some issues :

1. If I slide to an item, then zoom out and scroll to the first item, there are a space left before the first item :
   

2. If I zoom out, select an item, then zoom in (until the selected item goes out of the viewport), the selected item will be still displayed with the old position
   

3. at launch, there are one ListBoxItem realized, if I zoom out, of course more items will be realized. But if I zoom in again, the max number of ListBoxItem will remain (of course they will be empty). It should be better to flush those item.
   

To Reproduce
