## 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

static contextTypes = {
        test: PropTypes.string,

      render() {
        const child = (
          <b>
            <Text text={this.context.test} />
          </b>
        );
        if (this.props.prefix) {
          return [readText(this.props.prefix), child];
        }
        return child;
      }
    }
    await act(() => {
      const {pipe} = renderToPipeableStream(
        <TestProvider ctx="A">
          <div>
            <Suspense fallback={[<Text text="Loading: " />, <TestConsumer />]}>
              <TestProvider ctx="B">
                <TestConsumer prefix="Hello: " />
              </TestProvider>
              <TestConsumer />
            </Suspense>
          </div>
        </TestProvider>,
      );
      pipe(writable);
    });
