title: How to customize message text style in GtkMessageDialog with CSS?
body: <p>I am attempting to have a link show up in secondary text of the message dialog (with printf()-style), without an underline.
  I tried text-decoration: none; in the CSS to remove the link underline. Not worked.</p>
  
  <p>The CSS:</p>
  
  <pre><code>GtkMessageDialog a {
      text-decoration: none;
  }
  </code></pre>
  
  <p>How can I remove the underline from the link?</p>
