Setting default value to ArrayNode is not working

[tom10271]

Symfony: 4.3.2
Sylius: 1.5.2
PHP: 7.3.7

Consider this fixture

<?php

declare(strict_types=1);

namespace HBX\Fixture;

use Sylius\Bundle\CoreBundle\Fixture\AbstractResourceFixture;
use Symfony\Component\Config\Definition\Builder\ArrayNodeDefinition;

class ProductFixture extends AbstractResourceFixture
{
    public function getName(): string
    {
        return 'product';
    }

    protected function configureResourceNode(ArrayNodeDefinition $resourceNode): void
    {
        $resourceNode
            ->arrayNode('product_options')->scalarPrototype()->end()->end()
        ;
    }
}

In ProductExampleFactory

<?php

namespace App\Fixture\Factory;

use Symfony\Component\OptionsResolver\Options;
use Symfony\Component\OptionsResolver\OptionsResolver;

class ProductExampleFactory extends SyliusProductExampleFactory
{
    protected function configureOptions(OptionsResolver $resolver): void
    {
        parent::configureOptions($resolver);
        
        $resolver
            // ...

            // Never run
            ->setDefault('product_options', function (Options $options): array {
                $productOptions = $this->productOptionRepository->findAll();

                return [$productOptions[rand(0, count($productOptions) - 1)]];
            })

            // Actually even you set the default value direct, the resolved value is still an empty array only
            // ->setDefault('product_options', ['Wow'])
        ;
    }
}

I am not sure it is a SyliusFixtureBundle's bug or Symfony 4.3.3's bug

The problem should be Symfony will resolve $option to [] for ArrayNode, so in public function create(array $options = []): ProductInterface, $options['product_options'] is [] already making setDefault callback will not run.
