title: Wordpress Visual editor not working 4.9.6 - getting span code inside editor
body: <p>Wordpress visual editor not working after the update 4.9.6, I am getting only HTML code in the editor, not my text as normal. And also I am not able to write anything in the visual editor while text mode working fine for me.</p>
  
  <p>Here is code:</p>
  
  <pre><code>&lt;span style="display: inline-block; width: 0px; overflow: hidden; line- 
  height: 0;" data-mce-type="bookmark" class="mce_SELRES_start"&gt;&lt;/span&gt;
  </code></pre>
