Description

Hi,

I am trying to trace the root cause of https://github.com/ant-design/ant-design/issues/38818 ,
and I believe this is related to rc-motion, either being buggy on react-18, or maybe misused.

Here is a sandbox where I can repo the issue
https://codesandbox.io/s/small-moon-nigikp?file=/src/App.js

https://user-images.githubusercontent.com/1194083/203934195-bbaab64f-fd94-44c8-9b66-c292e4e6ceed.mov

as you can see, the element does not seems to end up in the state it is supposed to be, as sometimes Parent is hovered, but child is not visible

Research direction

Start with the linked CodeSandbox at src/App.js and reproduce the behavior under React 18. Trace how rc-motion handles the Parent hover and child visibility transitions; done means the element consistently reaches its expected state and the reproduced case no longer shows Parent hovered while the child is hidden.
