This requires significant reorganization of how Virtualization feature handles selection and due to the complexity of the TreeViewPanel (which virtualizes hierarchy of containers), such change is very risky for the performance and the memory of the control. We will address this scenario in documentation/KB - users will need to manually remove such items from the SelectedItems collection.

This one bit me again today. Grr. Is there any hope of this bug getting fixed? I have to jump through extra bookkeeping to try to manage this and now I discovered that the bookkeeping code has a bug. This is maddening.

I also had issue with adding to to a node with no children that the new child did not show up (using WPF) 
unless I set the ItemsSource to null and then back to the original ItemsSource.  I had no issue
with adding when the parent node had children.  Note
