      Description

      The reason for the regression is that PredicateTransitivePropagate looks at the FilterOperator below the ReduceSink.
      SemanticAnalyzer::genNotNullFilterForJoinSourcePlan was stacking another FilterOp for the not null check, so only that predicate was being applied transitively by PredicateTransitivePropagate.
