## 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
Link to code example:

It works well in react 18.2

expect(getVisibleChildren(container)).toEqual(<div>Loading...</div>);
    expect(ref.current).toBe(null);
    
    await waitForAll([]);
    
    expect(getVisibleChildren(container)).toEqual(<b>Error Message</b>);
    const b = container.getElementsByTagName('b')[0];
    expect(ref.current).toBe(b);
  });
