Can't override validation in SF4

[sbruev]

So, I'm trying to make a custom validation group. I've decided to test it with simple alteration to the registration validation rule, by increasing the min length to 6 characters. Right now my configuration is following:

# config/packages/fos_user.yaml

fos_user:
  db_driver: orm # other valid values are 'mongodb' and 'couchdb'
  firewall_name: main
  user_class: App\Entity\User
  from_email:
    address: "%mailer_user%"
    sender_name: "%mailer_user%"
  registration:
    form:
      type: FOS\UserBundle\Form\Type\RegistrationFormType
      validation_groups:  [CustomValidation]

# config/packages/validator/validation.yaml

FOS\UserBundle\Model\User:
  properties:
    username:
      - NotBlank:
          groups: [CustomValidation]
      - Length:
          min: 6
          minMessage: fos_user.password.short
          groups: [CustomValidation]

I've checked that the FOSUser config has updated with dump:config. I've run cache:clear. Yet the FOSUser ignores my config and continue to use the standard validation rules for registration (i.e. 2 chars min).

What am I missing here?

I have similar problem but with 8 chars as min length of password because of update
