## 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

Scheduler.log('[s!] ' + error.message);
            },
          },
        );
        pipe(writable);
      });
      assertLog(['[s!] Oops.']);
      const serverFallback = container.getElementsByTagName('p')[0];
      expect(serverFallback.innerHTML).toBe('Loading...');
      
      isClient = true;
      const root = ReactDOMClient.hydrateRoot(
        container,
        <App fallbackText="Loading..." />,
        {
          onRecoverableError(error) {
