	while (n) {
		Ref<SceneState> ss = (n == EditorNode::get_singleton()->get_edited_scene()) ? n->get_scene_inherited_state() : n->get_scene_instance_state();
		if (ss.is_valid()) {
			int path = ss->find_node_by_path(n->get_path_to(p_node));
			if (path != -1) {
				if (ss->is_node_in_group(path, p_group)) {
					can_edit = false;
				}

		}
		n = n->get_owner();
