<h3 id="summary-problem-motivation">Problem/Motivation</h3>
<p>While checking <a href="https://www.drupal.org/project/document_loader/issues/3580850">https://www.drupal.org/project/document_loader/issues/3580850</a>, I noticed that the MDXEditor's <strong>Editor.jsx (line 119)</strong> contains a leftover `my-classname` from when the app was initially implemented.</p>
<p>MDXEditor already provides toolbar specific classes, and this custom class is not necessary. It should be removed, also to prevent any usage of it.</p>
<h4 id="summary-steps-reproduce">Steps to reproduce (required for bugs, but not feature requests)</h4>
<p>Check <em>Editor.jsx</em> of MDXEditor or inspect the Editors toolbar on a textarea using the App. You will see the class is present, along with other more sensible class (`.mdxeditor-toolbar`) that should be used instead.</p>
