[GitHub] [incubator-echarts] CatWithWings opened a new issue #10471: expandAndCollapse 收缩前tree图渲染异常，旧分支没有擦除
CatWithWings opened a new issue #10471: expandAndCollapse 收缩前tree图渲染异常，旧分支没有擦除
URL: https://github.com/apache/incubator-echarts/issues/10471
### Version
4.2.1
### Steps to reproduce
echarts的tree，设置expandAndCollapse: true时关于收缩之后的data diff唯一的标识是如何确定的呢。当我的tree数据中有2个分支部分数据重复时，会出现收缩分支之后，原来旧的分支美誉被擦除，导致视图上出现许多多余分支，新旧分支试图重叠的现象。
### What is expected?
只出现收缩或展开后的新视图
### What is actually happening?
新旧视图同时出现
