    // NOTE: Although it was correct that removing event listeners associated with current node in Node::cleanup.
    // But it broke the compatibility to the versions before v3.16 .
    // User code may call `node->removeFromParent(true)` which will trigger node's cleanup method, when the node
    // is added to scene again, event listeners like EventListenerTouchOneByOne will be lost.
    // In fact, user's code should use `node->removeFromParent(false)` in order not to do a cleanup and just remove node
    // from its parent. For more discussion about why we revert this change is at
    // https://github.com/cocos2d/cocos2d-x/issues/18104. We need to consider more before we want to correct the old and
    // wrong logic code. For now, compatiblity is the most important for our users.
    //    _eventDispatcher->removeEventListenersForTarget(this);
