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
