Using `.. contents::` causes raw CSS to show up at the top of the page when using readme-renderer >= 37.0

```rst
=====
Title
=====

.. contents:: Table of Contents
    :depth: 2

Heading 1
---------
Description

Heading 2
~~~~~~~~~
Long text about this
```

Produces weird results (on top). `<body>` and `<style>` tags not opened/closed properly - result in a broken view.
