ItemsControl with ItemsSource+VirtualizedStackPanel : bad scrollbar position after removing some items (different items heights)

I have an ItemsControl with an ItemsSource and a VirtualizedStackPanel. Items have different heights. I move the scrollbar to the bottom of ItemsControls. I remove some items, so that scrollbar is still visible.
Resulting scrollbar position is invalid : only some of items which should be visible are on screen.
