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 requests = pendingTextRequests.get(text);
    if (requests !== undefined) {
      pendingTextRequests.delete(text);
      requests.forEach(resolve => resolve(text));
    }
  }
  function getAsyncText(text) {
    
    // 
    // 
    Scheduler.log(`Async text requested [${text}]`);
    return new Promise(resolve => {
      const requests = pendingTextRequests.get(text);
      if (requests !== undefined) {
        requests.push(resolve);
        pendingTextRequests.set(text, requests);
      } else {
        pendingTextRequests.set(text, [resolve]);
      }
    });
  }
  function Text({text}) {
