Description
当数据量较大时，同时使用expandedRowKeys控制展开，将会导致点击展开按钮时，展开动作很卡；
同时使用setState触发render的时候也会变卡。
比如：第一级数据 40条，第二级 10条 第三级 10条。

Research direction
Start with the linked CodeSandbox reproduction and trace table expansion with expandedRowKeys for the nested 40-by-10-by-10 dataset. Compare the expansion path with a setState-triggered render; done means expanding rows and updating state remain responsive with the reported large data volume.
