35744	Combine query support doesn't repoint nested external references	Simon Charette	Simon Charette	As I came to discover [https://forum.djangoproject.com/t/filtering-model-instances-m2m-field-to-exactly-match-another-m2m-field-or-list/34533/6 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.
