Recover from interrupted prefetch
AsyncPagingDataDiffer calculates the transformAnchorIndex and sends an access hint on that index after presenting the new list. This ensure prefetch distance will be fulfilled.

Fixed internally and will be available in paging 3.3.1
Description
However, in the rare case where the latest scroll position matches the last items of the newly refreshed list, there is no more scrollable distance. Without scrolling, RV does not trigger any bind/item access, and thus prefetch does not happen.
