I have same problem. It is empty until first scroll

[seeden]

It is caused by cache of usePositioner.
I fixed it with

  const nextIdRef = useRef(0);
  const currentKeys = useMemo(() => {
    return items
      .map(uniqueKey)
      .join(',');
  }, [items, uniqueKey]);

  const previousItems = usePrevious(items);
  const previousKeys = usePrevious(currentKeys);

  useMemo(() => {
    if (!previousItems) {
      return;
    }

    if (!previousItems.length && !items.length) {
      return;
    }

    if (previousKeys && currentKeys && currentKeys.startsWith(previousKeys)) {
      return;
    }

    nextIdRef.current += 1;
  }, [currentKeys, previousKeys, items, previousItems]);

  const positioner = usePositioner({
     ...
  }, [nextIdRef.current]);

uniquekey is function which returns unique id of the item (string)
