### 🖋 Description

如果父节点数据倒序排序，但是组内的数据无法倒序拍戏，如果组内的数据倒序排序，那么父节点的数据又无法正常排序？能否有方法让父子的指标同时倒序排序？
### 🔗 Reproduce Link

### 😊 Expected Behavior

### 😅 Current Behavior

Start by reproducing the behavior in a PivotSheet using @antv/s2 2.0.0-next.26 and the reported parent/child sorting scenario; no reproduction link or source file is provided. Trace the existing row-dimension sorting entry points and define completion as applying descending sorting consistently to both parent nodes and their grouped child nodes.
