      Context

      This bug was discovered during testing on the dedicated elegant step-down feature branch https://github.com/wiredtiger/wiredtiger/compare/develop...wt-17785-enable-elegant-stepdown-mainine. Currently, step-down restarts for test/format. In this branch, we are replacing the restart with a synchronous, elegant step-down triggered via reconfigure(role=follower). This ticket captures one of the bugs as a result of elegant stepdown.
