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.
await getAsyncText('Hi');
      return <Text text="Hi" />;
    }
    const root = ReactNoop.createRoot();
    await act(() => {
      startTransition(() => {
        root.render(<App />);
      });
    });
    assertLog(['Async text requested [Hi]']);
    await act(() => resolveTextRequests('Hi'));
    assertLog([
      // TODO: We shouldn't have to replay the function body again. Skip
      // straight to reconciliation.
      'Async text requested [Hi]',
      'Hi',
    ]);
    expect(root).toMatchRenderedOutput('Hi');
  });
  test('async child of a non-function component (e.g. a class)', async () => {
    class App extends React.Component {
