Isolate the currently selected items in the tree view.
This ensures that only the selected item and its ancestors remain visible, while

This function first makes all items in the tree visible to ensure a clean slate.
Then, it hides all items that are not currently selected by the user in the GUI tree view.
As a result, only the selected items remain visible in the 3D view, effectively isolating them.
