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.

   Returns whether passive effects were flushed.
   TODO: Combine this check with the one in flushPassiveEFfectsImpl. We should
   probably just combine the two functions. I believe they were only separate
