title: TinyMCE "EditMenuName" css property is not working after upgrading Episerver to version 11.5
body: <p>After upgrading <strong>Episerver</strong> to version 11.5, the <strong>TinyMCE</strong> feature of being able to set custom names for menu items in a drop down is no longer working.</p>
  
  <p>The special custom CSS attribute called <code>EditMenuName</code> is not working I guess. those menu items only showing particular CSS class names. not the names which are provided as "EditMenuName" attributes.</p>
  
  <p>How do I get this feature working again?</p>
