> We should avoid no-op empty relation propagation in AQE: if we convert an empty QueryStageExec to empty relation, it will further wrapped into a new query stage and execute -> produce empty result -> empty relation propagation again. This issue is currently not exposed because AQE will try to reuse shuffle.
