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 nextProps = workInProgress.pendingProps;
  const revealOrder: SuspenseListRevealOrder = nextProps.revealOrder;
  const tMode: SuspenseListTMode = nextProps.t;
  const newChildren = nextProps.children;
  validateRevealOrder(revealOrder);
  validateTOptions(tMode, revealOrder);
  validateSuspenseListChildren(newChildren, revealOrder);
  reconcileChildren(current, workInProgress, newChildren, renderLanes);
  let suspenseContext: SuspenseContext = suspenseStackCursor.current;
  const shouldForceFallback = hasSuspenseListContext(
    suspenseContext,
    (ForceSuspenseFallback: SuspenseContext),
  );
  if (shouldForceFallback) {
    suspenseContext = setShallowSuspenseListContext(
      suspenseContext,
      ForceSuspenseFallback,
    );
    workInProgress.flags |= DidCapture;
  } else {
    const didSuspendBefore =
      current !== null && (current.flags & DidCapture) !== NoFlags;
    if (didSuspendBefore) {
