Description
An OplogReplay query may perform a full collection scan if the collection has not been read from, but utilize the oplog start hack if the collection has been read from. This issue was introduced in 3.6 (it does not exist in 3.4). However, it does not appear to have been introduced by SERVER-29843, since the issue does not present at that time.
