title: Docusaurus font loading for text but not headings
body: <p>In my Docusaurus custom CSS file I have this code:</p>
  <pre><code>    @import url(&quot;https://fonts.googleapis.com/css2?family=Montserrat:ital,wght@0,400;0,500;0,600;0,700;1,400;1,500;1,600;1,700&amp;display=swap&quot;);
  :root {
      --ifm-color-primary: #25c2a0;
      --ifm-color-primary-dark: #29784c;
      --ifm-color-primary-darker: #277148;
      --ifm-color-primary-darkest: #205d3b;
      --ifm-color-primary-light: #33925d;
      --ifm-color-primary-lighter: #359962;
      --ifm-color-primary-lightest: #3cad6e;
      --ifm-code-font-size: 95%;
      --docusaurus-highlighted-code-line-bg: rgba(0, 0, 0, 0.1);
      font-family: &quot;Montserrat&quot;, sans-serif;
  }
  </code></pre>
  <p>This code is changing the regular text on my site, but it isn't changing headings. When I inspect the headings I see that the Montserrat font is crossed out, indicating that it is being overridden somewhere. Are heading styles set anywhere by default with Docusaurus?</p>
