In a custom hook, I forgot to wrap my `setState` call in a `useEffect`, which did not pose any problems prior to React 18 but now this does not work anymore. The component does not re-render if the store is changed back to its initial value. I guess this might be expected, but there was no warning whatsoever, so it was hard to find out.

So this is more like a question:
- Is that behavior a bug?
- If it is not, would it be useful to have a warning for another developer making the same mistake?

React version: 18
## Steps To Reproduce

1. Have a component use `useSyncExternalStore` (for example redux 8)
2. Call `setState` outside of `useEffect` or event handlers (in render)
3. Trigger a change to the store back and forth

Link to code example: https://codesandbox.io/s/react-18-redux-8-reproduce-bug-ojdx43

## The current behavior

- The component does re-render if the store value is updated to something different than its initial value
- The component **does not** re-render if the store is updated to its initial value again

## The expected behavior

- The component does re-render if the store value is updated to something different than its initial value
- The component **also does** re-render if the store is updated to its initial value again

## Further digging

When I tried to trace down the issue, I found that the `setState` called outside `useEffect` would mess up with the fiber update queue, in particular the prior `pushEffect` supposedly calling `updateStoreInstance` with the latest value to have the internal cached instance up to date. It does not get called at all (cancelled? overridden?) because of the unwrapped `setState`.

As a consequence, that cached instance never gets updated. Any other value but the initial value hence correctly triggers a re-render, as the `checkIfSnapshotChanged` ends up always comparing against that initial value.
