Comment:
As [https://docs.djangoproject.com/en/stable/ref/models/querysets/#union
per the documentation], ''"only LIMIT, OFFSET, COUNT(*), ORDER BY, and
specifying columns (i.e. slicing, count(), order_by(), and
values()/values_list()) are allowed on the resulting QuerySet."''. See
#27995 for a ticket to raise a helpful message about this and also a
ticket #28519 to support these features.
Duplicate of #28519.
