## 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);
    });
    expect(loggedErrors.length).toBe(1);
    expect(loggedErrors[0].message).toEqual('A0.1.1');
    expect(getVisibleChildren(container)).toEqual(
      <div>
        A0

        </div>
        A0
      </div>,
    );
  });
