Unexpected stuffing of elements into seemingly pseudo-logical (yet incorrect) properties

Found when writing template unit tests for Kittybox (which would only be possible by using this library to make sense of HTML without making behavior dependent on template layout).

Test snippet of HTML, generated by my unit tests and prettified by me:

<article class="h-entry">
  <header class="metadata">
    <div>
      <span>
        <a class="u-url u-uid" href="https://fireburn.ru/posts/est-eligendi-deleniti">
          <time class="dt-published" datetime="2022-05-16T20:41:45.032834285+03:00">Mon May 16 20:41:45 2022</time>
        </a>
      </span>
    </div>
  </header>
  <main class="e-content">
    <p>Aut repellat tempora. Incidunt dolorum earum iste. Quis velit necessitatibus numquam et quaerat recusandae. Eius harum maxime qui.</p>
  </main>
  <footer class="webinteractions">
    <ul class="counters">
      <li><span class="icon">❤️</span><span class="counter">0</span></li>
      <li><span class="icon">💬</span><span class="counter">0</span></li>
      <li><span class="icon">🔄</span><span class="counter">0</span></li>
      <li><span class="icon">🔖</span><span class="counter">0</span></li>
    </ul>
  </footer>
</article>
