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.

   commitRoot never returns a continuation; it always finishes synchronously.
   So we can clear these now to allow a new callback to be scheduled.
  root.callbackNode = null;
  root.callbackPriority = NoLane;
  root.cancelPendingCommit = null;
   Check which lanes no longer have any work scheduled on them, and mark
   those as finished.
  let remainingLanes = mergeLanes(finishedWork.lanes, finishedWork.childLanes);
   Make sure to account for lanes that were updated by a concurrent event
   during the render phase; don't mark them as finished.
  const concurrentlyUpdatedLanes = getConcurrentlyUpdatedLanes();
  remainingLanes = mergeLanes(remainingLanes, concurrentlyUpdatedLanes);
  markRootFinished(root, remainingLanes);
  if (root === workInProgressRoot) {
     W
    workInProgressRoot = null;
    workInProgress = null;
    workInProgressRootRenderLanes = NoLanes;
  } else {
     T

   If there are pending passive effects, schedule a callback to process them.
   Do this as early as possible, so it is queued before anything else that
   might get scheduled in the  (See #16714.)
   TODO: Delete all other places that schedule the passive effect callback
   They're redundant.
