Chrome scroll bar invalid after I use { Motion, spring } for sidebar slider switching

There is a sidebar in my program that uses the overflow-y:auto attribute

Then I tried to use ref to `focus()` and `forceupdate()` on the Slider component, but it didn't work. Even if` focus()` and `forceupdate()` are used long after the animation ends with `setTimeout()`, it is useless.

Later, I accidentally triggered a dispatch and the scroll bar returned to normal. I guess this is related to the view update of react
