SelectedItemChanged doesn't trigger after updating Items in FluentTreeView

[yermakovsergey]

Tried new feature #1945 , have some problems with SelectedItemChanged after updating Items provided to TreeViewItem

🐛 Bug Report

I'm generating some collection, with sub Items, providing this collection to TreeViewItem, tree works fine when I'm just navigating/collapsing/expanding/selecting - SelectedItemChanged event works.
When I'm moving sub item from one folder(parent item) to another, selecting item stop triggering SelectedItemChanged.
I've tried second way- after moving sub item tried to generate new collection, binded to TreeViewItem, SelectedItemChanged didn't work also.

💻 Repro or Code Sample

Make collection for Items providing, with sub item. After that make some changes in collection- move subitem between items, or make new collection with updated source. after that selection doens't trigger SelectedItemChanged.

🤔 Expected Behavior

I'm expecting that I can do update in Items provider collection and selection will work after that.

😯 Current Behavior

after updates in Items provider collection, selecting item doesn't triggered SelectedItemChanged.

💁 Possible Solution

maybe after Items provider update we can call some .Refresh() for FluentTreeView ref.

🔦 Context

In my case I'm using SelectedItemChanged to expose some details of selected tree item.
User have a dropdown with items sources selection so I need to have possibility to full update date source in Items.
Also when user can move items in tree.
