      We have some build failures related to duplicate values being inserted into the history store. At the moment, we've only ever seen this happening with full updates flagged with the WT_UPDATE_RESTORED_FROM_DS flag.

      This won't cause a visibility issue since it is a full update however, reinsertions of modifies could cause problems. We should add an additional assert to check whether the duplicate insert is a modify to better assess the severity of this bug.
