> Reason is that when {{LazilyInitializedUnfilteredRowIterator}} is closed the
> underlying iterator is nulled out, this allows the iterator to be
> re-initialized if anyone accesses a method that calls {{maybeInit}}, like
> {{isReverseOrder()}} which is called when adding an artificial range
> tombstone bound closer.
> This was caused by CASSANDRA-18398
