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.
node.sibling.return = node.return;
    node = node.sibling;
  }
   
   
  return true;
}
function markRootSuspended(root: FiberRoot, suspendedLanes: Lanes) {
   
   
   
   
  suspendedLanes = removeLanes(suspendedLanes, workInProgressRootPingedLanes);
  suspendedLanes = removeLanes(
    suspendedLanes,
    workInProgressRootInterleavedUpdatedLanes,
  );
  markRootSuspended_dontCallThisOneDirectly(root, suspendedLanes);
}
 This is the entry point for synchronous tasks that don't go
 through Scheduler
export function performSyncWorkOnRoot(root: FiberRoot): null {
  if (enableProfilerTimer && enableProfilerNestedUpdatePhase) {
    syncNestedUpdateFlag();
  }
  if ((executionContext & (RenderContext | CommitContext)) !== NoContext) {
    throw new Error('Should not already be working.');
  }
  flushPassiveEffects();
