BC break in LiveComponentHydrator

[1ed]

There is a BC break in LiveComponentHydrator as it now throws an exception when dehydrating a User entity class extending UserInterface.

In \Symfony\UX\LiveComponent\LiveComponentHydrator::dehydrateObjectValue the $classType parameter value is the interface not the class as it was before (in LegacyLivePropMetadata).

The component looks like this:

<?php

declare(strict_types=1);

namespace App\Component;

use App\Controller\BaseController;
use App\Entity\User;
use App\Form\Type\UserAdminType;
use Symfony\Component\Form\FormInterface;
use Symfony\UX\LiveComponent\Attribute\AsLiveComponent;
use Symfony\UX\LiveComponent\Attribute\LiveProp;
use Symfony\UX\LiveComponent\ComponentWithFormTrait;
use Symfony\UX\LiveComponent\DefaultActionTrait;

#[AsLiveComponent('user_admin_form')]
final class UserAdminForm extends BaseController
{
    use DefaultActionTrait;
    use ComponentWithFormTrait;

    #[LiveProp]
    public User $user;

    protected function instantiateForm(): FormInterface
    {
        return $this->createForm(UserAdminType::class, $this->user, ['is_edit' => true]);
    }
}
