Type infering breaks when groupBy omits table alias

[janedbal]

See following example, not sure this is possible to support or not.

$query = $em->createQueryBuilder()
	->addSelect('COUNT(m.id) AS count, m.intColumn')
	->from(Many::class, 'm')
	->join('m.one', 'o')
	->groupBy('intColumn'); // m.intColumn works

assertType(
	'array<array{count: int<0, max>|numeric-string, intColumn: int}>', // fails, is mixed
	$query->getQuery()->getResult()
);
