### Steps to reproduce

On an animation track using a bezier curve, select a key and try to change the handle mode from the inspector tab

### Minimal reproduction project

N/A
if (!root->has_node(animation->track_get_path(insert_key_from_track_call_track))) {
		EditorNode::get_singleton()->show_warning(TTR("Track path is invalid, so can't add a method key."));
		return;
	}
	Node *base = root->get_node(animation->track_get_path(insert_key_from_track_call_track));
	List<MethodInfo> minfo;
	base->get_method_list(&minfo);
	for (const MethodInfo &E : minfo) {
		if (E.name == p_method) {
			Dictionary d;
			d["method"] = p_method;
			Array params;
			int first_defarg = E.arguments.size() - E.default_arguments.size();
			for (int i = 0; i < E.arguments.size(); i++) {
				if (i >= first_defarg) {
					Variant arg = E.default_arguments[i - first_defarg];
					params.push_back(arg);
