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.
TODO (StrictEffects) Should we set a marker on the root if it contains strict effects
   so we don't traverse unnecessarily? similar to subtreeFlags but just at the root level.
   Maybe not a big deal since this is DEV only behavior.
  setCurrentDebugFiberInDEV(fiber);
  invokeEffectsInDev(fiber, MountLayoutDev, invokeLayoutEffectUnmountInDEV);
  if (hasPassiveEffects) {
    invokeEffectsInDev(fiber, MountPassiveDev, invokePassiveEffectUnmountInDEV);
  }
  invokeEffectsInDev(fiber, MountLayoutDev, invokeLayoutEffectMountInDEV);
  if (hasPassiveEffects) {
    invokeEffectsInDev(fiber, MountPassiveDev, invokePassiveEffectMountInDEV);
  }
  resetCurrentDebugFiberInDEV();
}

  firstChild: Fiber,
  fiberFlags: Flags,
  invokeEffectFn: (fiber: Fiber) => void,
) {
  let current: null | Fiber = firstChild;
  let subtreeRoot = null;
  while (current != null) {
    const primarySubtreeFlag = current.subtreeFlags & fiberFlags;
    if (
      current !== subtreeRoot &&
      current.child != null &&
      primarySubtreeFlag !== NoFlags
    ) {
      current = current.child;
    } else {
