Normalizers do not include extended object properties

[zexa]

example:

# api.raml
# minimized for brevity
types:
  Post: !include types/post.raml
  PublicPost: !include types/public-post.raml

# types/post.raml
#%RAML 1.0 DataType
displayName: Post item
type: object
properties:
  name:
    description: Post item name.
    type: string
    required: true
  content:
    description: Content of the post item.
    type: string
    required: true

# types/public-post.raml
#%RAML 1.0 DataType
displayName: Post item publicly available information
type: Post
properties:
  owner-id:
    description: Unique item id.
    type: string
    required: true
  id:
    description: Unique item id.
    type: string
    required: true

Generated PublicPostNormalizer results in

// minimized for brievity
class PublicPostNormalizer implements NormalizerInterface, DenormalizerInterface
{
    
    /**
     * @param array $data
     *
     * @return PublicPost
     */
    public function mapToEntity($data)
    {
        $entity = new PublicPost();

        if (isset($data['owner-id'])) {
            $entity->setOwnerId($data['owner-id']);
        }
        
        return $entity;
    }

    /**
     * @param PublicPost $entity
     *
     * @return array
     */
    public function mapFromEntity($entity)
    {
        return [
            'id' => $entity->getId(),
            'owner-id' => $entity->getOwnerId(),
            
        ];
    }
}

which lacks the required properties name and content defined in types/post.raml.
