renderHeaderCellContent not uses label from search/Model for GridView

[githubjeka]

<?=
GridView::widget(
    [
        'dataProvider' => $dataProvider,
        'filterModel' => $searchModel,
        'columns' => [
            ['class' => 'yii\grid\SerialColumn'],
            [
                'attribute' => 'pStatus',
                'format' => 'html',
                'value' => function ($data) {
                        return '<div class="label '
                        . $data->project->statuses[$data->project->status]['label'] . '">'
                        . $data->project->statuses[$data->project->status]['text'] . '</div>';
                    },
                'filter' => $searchModel->getPStatus()
            ],           
        ],
    ]
); ?>

namespace frontend\models\search;

use frontend\models\Object as ObjectModel;
use yii\helpers\ArrayHelper;

class Object extends ObjectModel
{

 public $pStatus;

 public function attributeLabels()
    {
        return ArrayHelper::merge(
            parent::attributeLabels(),
            [
                'project_date' => 'Дата проекта, не моложе',
                'pStatus' => 'Статус проекта',
            ]
        );
    }
}

// on view 
#   P Status //must be 'Статус проекта',

Attribute pStatus uses only in frontend\models\search\Object. Because it's set in frontend\models\Object not irrationally. But renderHeaderCellContent uses only attributeLabels from parent model .

It may be worth it to fix?

Was facing this issue too, I think this should be added to the core.
