Multiple ManyToMany on same class gives inconsistent results with GraphQL

[remyber]

API Platform version(s) affected: 3.0.6

Description
In an entity, I create several ManyToMany relations pointing to the same class. When retrieving data via a GraphQL query, all relations display the same results.

How to reproduce
Here is a minimalist entity affected by the bug:

#[ORM\Table(name: 'tests')]
#[ORM\Entity]
#[ApiResource(
    graphQlOperations: [new QueryCollection()]
)]
class Test
{
    #[ApiProperty(identifier: false)]
    #[ORM\Column(name: 'id', type: 'integer')]
    #[ORM\Id]
    #[ORM\GeneratedValue(strategy: 'AUTO')]
    private ?int $id = null;

    #[ApiProperty(identifier: true)]
    #[ORM\Column(type: 'uuid', unique: true)]
    private UuidInterface $uuid;

    #[ORM\JoinTable(name: 'tests_users1')]
    #[ORM\ManyToMany(targetEntity: User::class)]
    private iterable $users1;

    #[ORM\JoinTable(name: 'tests_users2')]
    #[ORM\ManyToMany(targetEntity: User::class)]
    private iterable $users2;

    public function __construct()
    {
        $this->uuid = Uuid::uuid4();

        $this->users1 = new ArrayCollection();
        $this->users2 = new ArrayCollection();
    }

    public function getId(): ?int
    {
        return $this->id;
    }

    public function getUuid(): UuidInterface
    {
        return $this->uuid;
    }

    public function getUsers1(): iterable
    {
        return $this->users1;
    }

    public function getUsers2(): iterable
    {
        return $this->users2;
    }

To test, I added an entry in tests_users2. tests_users1 is empty.
Here is the GraphQL query:

{
  tests {
    id
    users1 {
      collection {
        username
      }
    }
    users2 {
      collection {
        username
      }
    }
  }
}

And the results. The 2 relations show the same results, while users1 should be empty.

{
  "data": {
    "tests": [
      {
        "id": "/api/tests/92aaea46-def9-4cb6-84ee-ef8954c4a894",
        "users1": {
          "collection": [
            {
              "username": "test51"
            }
          ]
        },
        "users2": {
          "collection": [
            {
              "username": "test51"
            }
          ]
        }
      }
    ]
  }
}
