title: TinyMCE update content_style
body: <p>I'm using the Angular wrapper for TinyMCE 4, initializing the editor with some custom css like this:</p>
  
  <pre><code>editorInit: Settings = {
    menubar: false,
    statusbar: false,
    toolbar: false,
    content_style: '.highlight {background-color: #fff877;}'
  };
  </code></pre>
  
  <p>I'd like to dynamically change this content_style later, for example like this:</p>
  
  <pre><code>editor.settings.content_style = ".highlight {background-color: none;}";
  </code></pre>
  
  <p>However, this change is not being applied. Do I need to re-initialize the edior somehow everytime I want to change the content css?</p>
