## 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

writableA.write('<div id="container-A">');
            pipe(writableA);
            writableA.write('</div>');
          },
        },
      );
    });
    await act(() => {
      const {pipe} = renderToPipeableStream(
        <Suspense fallback={<Text text="Loading B..." />}>
          <Text text="This will show B: " />
          <div>
            <AsyncText text="B" />
          </div>
        </Suspense>,
        {
          identifierPrefix: 'B_',
          onShellReady() {
            writableB.write('<div id="container-B">');
            pipe(writableB);
            writableB.write('</div>');
          },
        },
      );
