 Hello.

 After updating to WordPress 4.9.6 I am getting a span code in the editor
 and the tabs don't switch.

 Here is code I'm getting:

 {{{#!php
 <?php
 <span style="display: inline-block; width: 0px; overflow: hidden; line-
 height: 0;" data-mce-type="bookmark" class="mce_SELRES_start"></span>
 }}}

 It is a WordPress core error or maybe some theme or plugin
 incompatibility?

 Thanks,
 Rogério Moreira
