Description
如何删除父节点，我为父节点设置 setOnItemChildClickListener，当我列表中只有一个父节点时，我去删除父节点报错，outofboundindex 错误，跟踪代码到
` // 先移除子项
removeCount = removeChildAt(position)
// 移除node自己
this.data.removeAt(position)
removeCount += 1
//这一步报错，我没有设置脚部，结果报错了
val node = this.data[position]
// 移除脚部
if (node is NodeFooterImp && node.footerNode != null) {
this.data.removeAt(position)
removeCount += 1
}
return removeCount`

Research direction
Start in BaseNodeAdapter at the parent-removal sequence shown in the issue, especially removeChildAt(position) and the later data[position] access. Reproduce it with one parent node, setOnItemChildClickListener, and no footer. Done means deleting that parent no longer raises an outofboundindex error.
