Symfony 4 : why the attributes of the 'first_options' doesn't apply in a form with a RepeatedType?

I'm doing a form with 2 fields to ask a password and to confirm the password.

I would like to have a message on the first field if the pattern is not the good one.

I tried to put attributes in 'options', the pattern goes to 2 fields, but the 'oninvalid' and 'oninput' goes only to the second field.

 $textInvalidFormat = $translator->trans('invalidFormat', [], 'general');
        $form = $this->createFormBuilder()
            ->add('password', RepeatedType::class, array(
                'type' => PasswordType::class,
                'options' => ['attr' => ['oninvalid'=>'setCustomValidity("' .$textInvalidFormat . '")',
                    'oninput'=>"setCustomValidity('')",
                    'pattern' => '^(?=.*\d)(?=.*[A-Z])(?=.*[a-z])(?=.*[^\w\d\s:])([^\s]){8,}$']],
                'first_options' => array(
                    'translation_domain' => 'request',
                    ),
                'second_options' => array('label' => 'field.request.secondpwd',
                    'translation_domain' => 'request',),
            ))
            ->getForm();

I also tried to put these options in the 'first_options' but the result is the same.

$textInvalidFormat = $translator->trans('invalidFormat', [], 'general');
        $form = $this->createFormBuilder()
            ->add('password', RepeatedType::class, array(
                'type' => PasswordType::class,
                'first_options' => array(
                    'translation_domain' => 'request',
                    'attr' => ['oninvalid'=>'setCustomValidity("' .$textInvalidFormat . '")',
                        'oninput'=>"setCustomValidity('')",
                        'pattern' => '^(?=.*\d)(?=.*[A-Z])(?=.*[a-z])(?=.*[^\w\d\s:])([^\s]){8,}$']
                    ),
                'second_options' => array('label' => 'field.request.secondpwd',
                    'translation_domain' => 'request',),
            ))
            ->getForm();

The result:

The problem is : I just have the message of my browser but not the one I define in my translation file.

Can you tell me where is the mistake and why the attributes of the 'first_options' doesn't apply ?
