Describe the bug

If you wanna disable some elements in choice type but you wanna still show it, you can't. Actually, if you set element as disabled it will set as hidden

To Reproduce

1. Go to product detail in administration
2. Open file ProductFormType in your IDE
3. into brand element add these lines

            ->add('brand', ChoiceType::class, [
                'required' => false,
                'choices' => $this->brandFacade->getAll(),
                'choice_label' => 'name',
                'choice_value' => 'id',
+               'choice_attr' => function (Brand $brand) {
+                   return [
+                       'disabled' => 'disabled',
+                   ];
+               },
                'placeholder' => t('-- Choose brand --'),
                'label' => t('Brand'),
            ])

5. Refresh page with product detail in administration
6. Open brand choice list and see nothing
