@Template annotation generate wrong path

When you have controller named with two or more words (e.g. StaticPageController) and use @Template annotation it generated folder StaticPage in views, but Symfony expects static_page.

Steps to reproduce

1. Create this controller

class StaticPageController extends Controller
{
    /**
     * @Route("/about-us", name="about-us")
     * @Template
     */
    public function aboutUsAction()
    {
    }
}

1. Use function “Twig: Create Template” (It creates Resources/views/StaticPage/AboutUs.html.twig)
2. Run server
3. Go to address /about-us

What is the result

Error message “Unable to find template “AppBundle/static_page/about_us.html.twig””

What should be the result

Plugin should generate folders and files with snake_case, not with camelCase (it is also written here in best practices)

Blast from the past, I have no idea.

I’d try to add it to ide-twig.json (example)
