Richcombo seems to break on html entities in values

• configure an editor with latest strinsert addon from ​https://github.com/57u/custom-dropdown-ckeditor4/commit/32bb75a5fc5129722ddd32637e8639be2735cbb5 (​http://ckeditor.com/addon/strinsert is not up to date) using following settings:

  config.extraPlugins = 'strinsert';
  config.strinsert_strings = [{'name': 'test', 'value': 'html entities like <, &gt and & wont work'}];
  

• open the editor, select 'test' from the 'Insert' dropdown in the toolbar and you'll get a JavaScript error like:
  • Chrome:

    Uncaught TypeError: Cannot call method 'hasClass' of null ckeditor.js:746

    onclick
