Bug Report

DQL with simple entity alias in SELECT part return string instead of enum instance (in HYDRATE_ARRAY mode).

Q	A
BC Break	no
Version	2.12.x

Current behavior

#[Entity]
class Animal
{
    #[Column, Id, GeneratedValue]
    public int $id = 0;

    #[Column]
    public Status $status = Status::OK;
}

enum Status: string
{
    case OK = 'OK';
    case ERROR = 'ERROR';
}

class AnimalRepository
{
    public function __construct(private readonly EntityManagerInterface $entityManager)
    {
    }

    public function test(): void
    {
        // animal.status is Status enum - OK
        $items1 = $this->entityManager->createQueryBuilder()
            ->select('animal')
            ->from(Animal::class, 'animal')
            ->getQuery()
            ->getResult();

        // animal.status is string - BUG
        $items2 = $this->entityManager->createQueryBuilder()
            ->select('animal')
            ->from(Animal::class, 'animal')
            ->getQuery()
            ->getResult(AbstractQuery::HYDRATE_ARRAY);

        // animal.status is Status enum - OK
        $items3 = $this->entityManager->createQueryBuilder()
            ->select('animal.id, animal.status')
            ->from(Animal::class, 'animal')
            ->getQuery()
            ->getResult();

        // animal.status is Status enum - OK
        $items4 = $this->entityManager->createQueryBuilder()
            ->select('animal.id, animal.status')
            ->from(Animal::class, 'animal')
            ->getQuery()
            ->getResult(AbstractQuery::HYDRATE_ARRAY);
    }
}

Expected behavior

DQL with SELECT entity as root (+ ArrayHydrator) should returns instance of enum.
