body: <p>Initial setup:</p>
  <pre class="lang-html prettyprint-override"><code>&lt;link rel=&quot;stylesheet&quot; href=&quot;https://fonts.googleapis.com/css2?family=Montserrat:wght@400;700&amp;amp;display=swap&quot;&gt;
  </code></pre>
  <pre class="lang-css prettyprint-override"><code>html {
      font-family: Montserrat, sans-serif
  }
  </code></pre>
  <p>Looks bad when <code>[lang]</code> is set to <code>'ru'</code> or any other value:</p>
  <pre class="lang-html prettyprint-override"><code>&lt;html lang='ru'&gt;
  </code></pre>

  <p>I faced this issue only on my iPhone with iOS 14.0.1 in any web browser (since all browsers on iOS is based on WebKit).</p>
  <p>It is not reproduced on Safari 14 on macOS, or any other browser.</p>
