Fixes #31653.

A hydration error occurs when using useId with a parent that has a render phase update. @gnoff and @sebmarkbage fixed this for React 19 in #25713.

React 18 will have users for some time, and we are encountering this issue in production. For these reasons, I think it is a good idea to backport that fix to React 18.

I am definitely not a React contributor nor familiar with its internals, so this may be unwanted or an incorrect solution. I also apologize if I used the wrong base branch for a new release.

Consideration appreciated!

A hydration error occurs when using `useId` with a parent that has a render phase update. This has already been fixed in React 19 by facebook#25713.

React 18 will have users for some time, and this issue is showing up in production. Therefore, this backports that fix to React 18.

Fixes facebook#31653.

Is there any chance for merge for next patch release in react@18? Seems like formality - since the same solution is already merged for react@19 ?
