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. 
if (currentUpdateQueue !== null) {
        const currentMemoCache: ?MemoCache = currentUpdateQueue.memoCache;
        if (currentMemoCache != null) {
          memoCache = {
            data: currentMemoCache.data.map(array => array.slice()),
            index: 0,
          };
        }
      }
    }
  }
   Finally fall back to allocating a fresh instance of the cache
  if (memoCache == null) {
    memoCache = {
      data: [],
      index: 0,
    };
  }
  if (updateQueue === null) {
    updateQueue = createFunctionComponentUpdateQueue();
    currentlyRenderingFiber.updateQueue = updateQueue;
  }
  updateQueue.memoCache = memoCache;
  let data = memoCache.data[memoCache.index];
  if (data === undefined) {
    data = memoCache.data[memoCache.index] = new Array(size);
    for (let i = 0; i < size; i++) {
      data[i] = REACT_MEMO_CACHE_SENTINEL;
    }
  } else if (data.length !== size) {
