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 dedupeKey = renderingComponentName;
          if (!didWarnAboutUpdateInRenderForAnotherComponent.has(dedupeKey)) {
            didWarnAboutUpdateInRenderForAnotherComponent.add(dedupeKey);
            const setStateComponentName =
              getComponentNameFromFiber(fiber) || 'Unknown';
            console.error(
              'Cannot update a component (`%s`) while rendering a ' +
                'different component (`%s`). To locate the bad setState() call inside `%s`, ' +
                'follow the stack trace as described in https:reactjs.orglinksetstate-in-render',
              setStateComponentName,
              renderingComponentName,
              renderingComponentName,
            );
          }
          break;
        }
        case ClassComponent: {
          if (!didWarnAboutUpdateInRender) {
            console.error(
              'Cannot update during an existing state transition (such as ' +
                'within `render`). Render methods should be a pure ' +
                'function of props and state.',
            );
            didWarnAboutUpdateInRender = true;
          }
          break;
        }
      }
    }
  }
