<h3 id="summary-problem-motivation">Problem/Motivation</h3>
<p>On gin_preprocess_breadcrumb() $node is not always instanceof NodeInterface and it breaks the administration page.</p>
<h4 id="summary-steps-reproduce">Steps to reproduce</h4>
<ol>
<li>Create an administration view with a url that contains a "%node" route parameter and a Content:ID as contextual filter.</li>
<li>Visit the url of the created view</li>
</ol>
<p>The following error appears:</p>
<blockquote><p>
