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 act(() => {
      root.render(<App contextValue={<Child text="A" />} />);
    });
    assertLog(['Indirection', 'ParentOfContextNode', 'A', 'Mount']);
    expect(root).toMatchRenderedOutput('A');
    // Update the child to a new value
    await act(async () => {
      root.render(<App contextValue={<Child text="B" />} />);
    });
    assertLog([
      // Notice that the <Indirection /> did not rerender, because the
      // update was sent via Context.
      // TODO: We shouldn't have to re-render the parent of the context node.
      // This happens because we need to reconcile the parent's children again.
      // However, we should be able to skip directly to reconcilation without
      // evaluating the component. One way to do this might be to mark the
      // context dependency with a flag that says it was added
      // during reconcilation.
      'ParentOfContextNode',
      // Notice that this was an update, not a remount.
      'B',
    ]);
    expect(root).toMatchRenderedOutput('B');
    // Delete the old child and replace it with a new one, by changing the key
    await act(async () => {
      root.render(<App contextValue={<Child key="C" text="C" />} />);
    });
    assertLog([
      'ParentOfContextNode',
      // A new instance is mounted
