condition options takes no effect for related models attributes in ngRestExtraAttributeTypes

[Webkadabra]

condition option does not work in ngRestExtraAttributeTypes for values of related models. Code:
Product.php:

public function ngRestExtraAttributeTypes() {
        return [
            'shippingConfig' => 'angular', // MUST BE `angular`, because `hidden` would not send values to client
            'shippingConfig.is_tilt_allowed' => ['toggleStatus'],
            'shippingConfig.weight' => ['number'],
            'shippingConfig.length' => ['number'],
            'shippingConfig.width' => ['number'],
            'shippingConfig.height' => ['number', 'condition' => '{is_shipping_enabled}==1'],
        ];
    }

   public function getShippingConfig() {
        return $this->hasOne(ShopProductShippingConfig::class, ['product_id' => 'id']);
    }

public function ngRestScopes() {
        return [
            ['list', ['name', 'sku', 'producer_id', 'qty_available', 'is_active', 'is_shipping_enabled', 'is_in_stock', 'is_on_sale',]],
            [['create', 'update'], ['name', 'sku', 'permalink', 'producer_id', 'adminCollections', 'adminSets', 'qty_available', 'is_active', 'is_in_stock', 'is_on_sale',
                'is_shipping_enabled',
                'shippingConfig',
                'shippingConfig.is_tilt_allowed',
                'shippingConfig.weight',
                'shippingConfig.length',
                'shippingConfig.width',
                'shippingConfig.height', ]],
            ['delete', false],
        ];
    }

The shippingConfig.height field becomes always invisible.
