## React version
React version: 18.3.0-next-b0671f9ea-20230130

## Problem
In `StrictMode`,  when using hydrateRoot to render a component that using `useSyncExternalStore` it seems that useSES will do hydration twice. 

But in second hydration process,  useSES does not use the result of `getServerSnapshot` as initial state, which will cause hydration error.

This problem will only happen in `development` mode, 

## Reproduce

It works well in react 18.2

      pipe(writable);
