Not within the above issues！

Is the selected node collapsed? Would expanding the parent node first make this realized and then you can scroll into view ?

This issue still exists.

No, can not scroll into view. I think because ui virtualizationv.
Before the first expand,the visual tree has not yet been implemented,like wpf treeview,but wpf can realize by additional behavior,yet can not find the same event Selected in winui TreeViewItem.
