      Capped collections perform un-timestamped writes to delete expired documents in FCV <= 4.4, but all documents will have had an assigned timestamp when first inserted. This breaks contracts with the storage engine regarding mixed-use timestamps and means that point-in-time reads do not work correctly on capped collections.

      As a result, background validation when reading documents that have just been deleted.
