      On the retryable_writes_jscore_stepdown suite, we've seen how a collection is created, then rollbacked, and finally, the operation is not being retried. The cluster is not sending any error to the driver, so the driver believes the operation has been successfully created.

      This ticket's goal is to investigate whether this is a real bug or if it's just related to the retryable_writes_jscore_stepdown suite.

      You'll find attached to this ticket a BF with the logs of an occurrence.
