Current Behaviour

I know, its getting annoying with my issues :)
I found another case I've got sometimes. When the controller has an array return type it doesn't get updated to Response.

    /**
     * @return array
     */
    public function indexAction(): array
    {
        return $this->render('AppBundle:Module:index.html.twig');
    }

Minimal PHP Code Causing Issue

    /**
     * @Template("AppBundle:Module:index.html.twig")
     *
     * @return array
     */
    public function indexAction(): array
    {
        return [];
    }

Expected Behaviour

    /**
     * @return Response
     */
    public function indexAction(): \Symfony\Component\HttpFoundation\Response
    {
        return $this->render('AppBundle:Module:index.html.twig');
    }
