TreeView.SelectionChanged event not fired when invoking UnselectAll

[AngryCarrot789]

Describe the bug

When I call UnselectAll on my tree view, the selected items list gets called but no event is fired.

To Reproduce

Create a TreeView and fill it with some TreeViewItems. Then select an item and invoke UnselectAll, you will notice no SelectionChanged event is fired

Expected behavior

No response

Avalonia version

11.2.999-cibuild0048720-alpha

OS

Windows

Additional context

I insert TreeViewItems into the TreeView manually: this.Items.Insert(0, new TreeViewItem());. Maybe there is an issue with this technique?

Seems like the TreeView.SelectedItemsCollectionChanged method in the NotifyCollectionChangedAction.Reset case is checking if SelectedItems list has items which it wont since it's responding to a CollectionChanged event from said list
