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
List<String> scenes;
	int current_tab = scene_tabs->get_current_tab();
	for (int i = 0; i < p_resources.size(); i++) {
		String file_type = ResourceLoader::get_resource_type(p_resources[i]);
		if (file_type == "PackedScene") {
			scenes.push_back(p_resources[i]);
			
			continue;
		}
		if (!ResourceCache::has(p_resources[i])) {
			
			continue;
		}
		
		Ref<Resource> resource = ResourceCache::get_ref(p_resources[i]);
		if (resource.is_valid()) {
			resource->reload_from_file();
		}
	}
	for (const String &E : scenes) {
		reload_scene(E);
		reload_instances_with_path_in_edited_scenes(E);
	}
	scene_tabs->set_current_tab(current_tab);
}
