Symfony 5 form handle request is executing the same query twice - php

Question

So I'm starting a new Symfony 5 application, and having some trouble in a editing controller, imho, symfony is executing a dumb query.
So, below is the code of my controller and where is executing duplicate query and the queries. If anyone could help me out, would be very thankfull, If more code is needed, please let me know.
The repeated query, just occurs when submiting the request, not getting it. So just in the POST method.
EDIT: So... I found out, something that is causing, in formtype 'by_reference'=> false, but I want to use it. So I could solve it in a ugly way, doing:
$product = $this->productRepository->find($id);
$product->getImages()->initialize();
It looks like, if I pre load entity, it works fine, maybe because of something that by reference does, not take from entity cache, like the example in docs:
From symfony docs: https://symfony.com/doc/current/reference/forms/types/collection.html
// If you set by_reference to false, submitting looks like this:
$article->setTitle('...');
$author = clone $article->getAuthor();
$author->setName('...');
$author->setEmail('...');
$article->setAuthor($author);
class ProductController extends AbstractController
{
public function editProduct(Request $request, int $id)
{
// Here it executes the query for getting the product, its ok
$product = $this->productRepository->find($id);
// Here it executes the query of the images, for handling the forms
$form = $this->createForm(ProductType::class, $product);
// Here is the problem, it executes the same query AGAIN!
$form->handleRequest($request);
}
}
So, I don't know why when I call $form->handleRequest(), It executes a query, that already runned, bellow is some usefull code, that maybe I mess up.
Query runned twice:
SELECT t0.id AS id_1, t0.image AS image_2, t0.product_id AS product_id_3 FROM product_image t0 WHERE t0.product_id = ?
