How to throw an exception that will be handled by ErrorHandler?

Question

Yii

Here I have created a filter

class FilterBannedIp extends ActionFilter {
    public function events() {
        return [Controller::EVENT_BEFORE_ACTION => 'beforeAction'];
    }

    public function beforeAction($event) {
        $bannedIp = BannedIp::findByIp(Yii::$app->request->getUserIP());

        if ($bannedIp && $bannedIp->isBanned(Yii::$app->request->getUserIP())) {
            throw new ForbiddenHttpException('Ваш IP заблокирован');
            return false;
        }

        return true;
    }
}

Here I screw it to the controller

public function init() {
    $this->attachBehavior('filterBannedIp', FilterBannedIp::className());
}

And here is what I get

exception 'yii\web\ForbiddenHttpException' with message 'Ваш IP заблокирован' in C:\OpenServer\domains\work2\basic\filters\FilterBannedIp.php:22

How can I raise an exception that will be handled by the ErrorHandler and displayed on a special page? As I understand it, this is what happens to me, but then the ErrorAction also blocks? Then how to get around it?
