## 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

typeof reducer === 'function' ? reducer : (basicStateReducer: any);
  return updateReducerImpl(hook, ((currentHook: any): Hook), resolvedReducer);
}
function rerenderOptimistic<S, A>(
  passthrough: S,
  reducer: ?(S, A) => S,

  if (currentHook !== null) {
    
    return updateOptimistic(passthrough, reducer);
  }
   This is a mount. No updates to process.
  const hook = updateWorkInProgressHook();
  
  
  hook.baseState = hook.memoizedState = passthrough;
  const dispatch = hook.queue.dispatch;
  return [passthrough, dispatch];
}
