<h3 id="summary-problem-motivation">Problem/Motivation</h3>
<p>In some situations link text that is passed to <code>HtmlTitleFilter::decodeToMarkup()</code> will be an array. This can happen when this module will be used together with <code>current_page_crumb</code> module. Title for the page is provided by <code>title_resolver</code> core service and is used by <code>current_page_crumb</code> module. <code>TitleResolverInterface::getTitle</code> documents that some times returned title could actually be a render array. </p>
<h4 id="summary-steps-reproduce">Steps to reproduce</h4>
<ol>
<li>Install this module and <code>current_page_crumb</code> module. </li>
<li>Log into the website( assuming you are landed on /user/%user page)</li>
<li>You should see :<br>

<p>Add a check to call to <code>HtmlTitleFilter::decodeToMarkup()</code> in <code>html_title_preprocess_breadcrumb()</code> that the text that’s about to be passed to <code>HtmlTitleFilter::decodeToText()</code> is actually string-ish.</p>
