[GitHub] [incubator-echarts] CatWithWings opened a new issue #10470: expandAndCollapse 收缩前tree图渲染异常，旧分支没有擦除

CatWithWings opened a new issue #10470: 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/10470
 
 
   Version
   4.2.1
   
   问题重现：
   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。
