"Using $this outside a class" in views templates

In Yii2 templates, like this:

```
<?php

/* @var $this yii\web\View */
/* @var $form yii\bootstrap\ActiveForm */
/* @var $model App\Model\Foo */

echo $this->title;
```

PHPStan displays error about "Using $this outside a class".

Is there a way to fix this without fully ignoring this error message? Like disabling rule for specified directory?
