1305 SAVEPOINT does not exist

I am using transactions in my code and I am using the RefreshDatabase trait. This one creates a transaction of its own and then the rest of my transactions inside are performed by using MySQL savepoints. I found the relevant code which is in Illuminate\Database\Concerns\ManageTransactions.

The problem is, that even when I tried to rollback to the savepoint right after it was created, it always throws that error.

ManageTransactions:127

/**
 * Create a save point within the database.
 *
 * @return void
 */
protected function createSavepoint()
{
    $this->getPdo()->exec(
        $this->queryGrammar->compileSavepoint('trans'.($this->transactions + 1))
    );
    $this->getPdo()->exec(
        $this->queryGrammar->compileSavepointRollBack('trans'.($this->transactions + 1))
    );
}

I even tried if it was a mysql error but it works fine with the following code

START TRANSACTION;
SAVEPOINT trans2;
select count(*) as aggregate from `users` where `id` = 1 and `users`.`deleted_at` is null;
ROLLBACK TO SAVEPOINT trans2;
