      SERVER-95330 caused a regression that makes some of the anomalies stated on SERVER-84723 reappear. Specifically, these anomalies can happen when reading from the renamed-from collection, but not for other DDLs such as drop/resharding, or rename when reading from the renamed-to collection.

      This affects version v8.2 and master exclusively.
