My fix for #26058 in #27066 also addresses this issue. When `EliminateCrossJoin` rebuilds the joins, it preserves the NULL semantics of each join key, so the outer `=` no longer overrides the inner `IS NOT DISTINCT FROM`. I added a regression test in `joins.slt` that checks the row with matching NULL keys is retained. -- This is an automated message from the Apache Git Service.
