Hmmm, it’s not coming through for me. My wordpress generates:
<article class="comment-body">
<footer class="comment-meta">
<div class="comment-author vcard">
<img alt="Avatar for Skye" src="https://forum.example.com/user_avatar/forum.example.com/skye/64/3_2.png" class="avatar avatar-64 photo avatar-default" height="64" width="64">
<b class="fn"><a href="https://forum.example.com/t/test-post-for-discourse/57" rel="external" class="url">Skye</a></b>
<span class="says screen-reader-text">says:</span><!-- screen reader text -->
</div>
<div class="comment-metadata">
<time datetime=""></time>
</div>
</footer>
<div class="comment-content"><p>Test comment. This is a test comment with <strong>bold text</strong>.</p></div>
</article>
