`KeepLastItemInView` does not work for `ListView`

[xperiandri]

I need a chat like ListView.

According to this sample this must be achieved by

<ItemsPanelTemplate>
  <ItemsStackPanel VerticalAlignment="Bottom" ItemsUpdatingScrollMode="KeepLastItemInView" />
</ItemsPanelTemplate>

Current behavior

But the ListView does not scroll to the last item

Expected behavior

ListView is scrolled to the last item when added

How to reproduce it (as minimally and precisely as possible)

Workaround

Write your own logic to do scrolling
