### 🐛 Bug description [Please make everyone to understand it]

demo：
https://codesandbox.io/s/determined-kapitsa-tu258h?file=/index.ts

tooltips的联动 出现了闪烁， 有时tooltips 不展示(内环 hover 值为2 的 元素，外环的 tooltip 不会触发)

### 📷 Step to reproduce

进demo 移动鼠标展示 tooltips 会出现 闪烁

Start with the linked CodeSandbox demo and reproduce the tooltip flicker by hovering nested pie slices, including the inner-ring value 2 case. Trace the tooltip linkage for the nested pie chart; done means hovering slices consistently displays the expected inner- and outer-ring tooltips without flickering.
