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.
if (__DEV__) {
    reportUncaughtErrorInDEV(error);
    setIsRunningInsertionEffect(false);
  }
  if (sourceFiber.tag === HostRoot) {
     Error was thrown at the root. There is no parent, so the root
     itself should capture it.
    captureCommitPhaseErrorOnRoot(sourceFiber, sourceFiber, error);
    return;
  }
  let fiber = nearestMountedAncestor;
  while (fiber !== null) {
    if (fiber.tag === HostRoot) {
      captureCommitPhaseErrorOnRoot(fiber, sourceFiber, error);
      return;
    } else if (fiber.tag === ClassComponent) {
      const ctor = fiber.type;
      const instance = fiber.stateNode;
      if (
        typeof ctor.getDerivedStateFromError === 'function' ||
        (typeof instance.componentDidCatch === 'function' &&
          !isAlreadyFailedLegacyErrorBoundary(instance))
      ) {
        const errorInfo = createCapturedValueAtFiber(error, sourceFiber);
        const update = createClassErrorUpdate(
          fiber,
          errorInfo,
          (SyncLane: Lane),
        );
        const root = enqueueUpdate(fiber, update, (SyncLane: Lane));
