Description (last modified by Simon Charette)

As I came to discover ​trying to help someone on the forum the support for correlated subqueries (aka OuterRef) in combined queries (union, intersection, difference) added in #29338 fails to re-point external references on relabeling (an operation performed on subquery pushdown to prevent table name collisions) causing nested outer query references to be orphaned.
