### Steps to reproduce

打开控制台，拖拽最后一节的000701节点到这一节的最上端（000702）上方。在控制台可以看到两个输出，一个是allowDrop事件中的dropPosition，值为0，另一个是在onDrop事件中的dropPosition中的值，为5。明显计为了上一层级的index。

### What is expected?

onDrop事件的dropPosition输出当前层级的index。

### What is actually happening?

上一层级的index

另外，在Tree的相关文档中，allowDrop事件中，缺少了dragNode字段，在onDrop事件中，缺少了dropPosition字段。
