In the Claro theme's page.html.twig, the page-specific header (with the page title and breadcrumb) has been moved to inside the landmark.
The target for the skip-link has been moved to be the first child of the landmark.

    <div class="layout-container">

    </div>
  </header>

  <div class="layout-container">
    {{ page.pre_content }}
    <main class="page-content clearfix" role="main">
      <div class="visually-hidden"><a id="main-content" tabindex="-1"></a></div>
      {{ page.highlighted }}
      {% if page.help %}
        <div class="help">
          {{ page.help }}
        </div>
      {% endif %}
