## 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

errors.push(error.message);
        },
      });
      await waitForAll([]);
      expect(errors).toEqual([]);
      expect(getVisibleChildren(container)).toEqual(
        <div>
          hello<b>world</b>
        </div>,
      );
    });
    it('it does not prepend a text separators if the segments first emission is a non-Text Node', async () => {
      function App() {
