### 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
Variant old = animation->track_get_key_value(track, key);
				setting = true;
				String action_name;
				switch (animation->track_get_type(track)) {
					case Animation::TYPE_POSITION_3D:
						action_name = TTR("Animation Change Position3D");
						break;
					case Animation::TYPE_ROTATION_3D:
						action_name = TTR("Animation Change Rotation3D");
						break;
					case Animation::TYPE_SCALE_3D:
						action_name = TTR("Animation Change Scale3D");
						break;
					default: {
					}
				}
				undo_redo->create_action(action_name);
				undo_redo->add_do_method(animation.ptr(), "track_set_key_value", track, key, p_value);
				undo_redo->add_undo_method(animation.ptr(), "track_set_key_value", track, key, old);
				undo_redo->add_do_method(this, "_update_obj", animation);
				undo_redo->add_undo_method(this, "_update_obj", animation);
				undo_redo->commit_action();
				setting = false;
				return true;
			}
		} break;
		case Animation::TYPE_BLEND_SHAPE:
		case Animation::TYPE_VALUE: {
			if (name == "value") {
				Variant value = p_value;
