React version: 18.3.0-next-3ba7add60-20221201

Hard to reproduce.

In Next.js, in rare cases, and only after a fast refresh, the ref object when using forwardRef is simply `{}`.

This leads to the `TypeError: can't define property "current": Object is not extensible` error when used with `useImperativeHandle`.

```tsx
function Parent() {
  const carouselRef = useRef<any>();

  return <Suspense><Carousel ref={carouselRef} /></Suspense>
}

const Carousel = forwardRef((props, ref) => {
  if (!('current' in ref)) { debugger; }
  const thing = use(aPromise);
  return ...;
});
```

In `updateImperativeHandle`, the ref is already an empty object.

I haven't investigated it further yet, the stacktraces are quite hard to follow.
const nextChildren = nextState.element;
  if (supportsHydration && prevState.isDehydrated) {
     
     
     
     
    const overrideState: RootState = {
      element: nextChildren,
      isDehydrated: false,
      cache: nextState.cache,
    };
    const updateQueue: UpdateQueue<RootState> =
      (workInProgress.updateQueue: any);
     `baseState` can always be the l state because the root doesn't
     have reducer functions so it doesn't need rebasing.
    updateQueue.baseState = overrideState;
    workInProgress.memoizedState = overrideState;
    if (workInProgress.flags & ForceClientRender) {
       
       
      const recoverableError = createCapturedValueAtFiber<mixed>(
        new Error(
          'There was an error while hydrating. Because the error happened outside ' +
            'of a Suspense boundary, the entire root will switch to ' +
            'client rendering.',
        ),
        workInProgress,
      );
