[Bug] [Have a solution] Attribute mutators doesnt work with Translatable entity when its empty Relation subfield in Relationship field

Bug report

I wrote about this comment, but for reliability, I will duplicate it. It seems to me that this is a rather serious problem for those who use translatable models.

What I did

Make model MultipleEventResponse

    public $translatable = ['text'];

    public function setTextAttribute($value){ //its just simple example
        if ($value!=null){
            $this->attributes['text'] = $value; 
        }
    }

Make reationship field in parent entity controller Multiple Event

    public function responses()
    {
        return $this->hasMany(MultipleEventResponse::class);
    }

  CRUD::addField([   // relationship
            'label'=>'Answers',
            'type' => "relationship",
            'name' => 'responses',
            'subfields'   => [
                [
                    'label'=>'Question',
                    'name' => 'text',
                    'type' => 'textarea',
                    'wrapper' => [
                        'class' => 'form-group col-md-3',
                    ],
                ],

What I expected to happen
