In BF-33263 we have two index scans. If one plan happens to yield, it calls abandonSnapshot() which by default does a WT rollback_transaction and resets all positioned cursors. The other plan is now using an invalid cursor. This bug only manifests probabilistically unless internalQueryExecYieldIterations is set to 1 and is only caught by ASAN.
