Regression from #72277 (most likely, I didn't test)

### Steps to reproduce

1. Add some Node to your scene
2. Add a TileMap as a child
3. Select TileMap
4. Fold its parent in the scene tree
5. Restart the editor
6. The TileMap selection is restored and so is the folded node, resulting in a weird paradox

### Minimal reproduction project

N/A
if (player && player == p_node) {
		player = nullptr;
		set_process(false);
		track_editor->set_animation(Ref<Animation>(), true);
		track_editor->set_root(nullptr);
		track_editor->show_select_node_warning(true);
		_update_player();
	}
}
