title: how to remove title attribute from tinymce textarea
body: <p>I am using jquery-ui tooltip and tinimce 4,</p>
  
  <p>the problem is when tinymce is loaded in a textarea there is the title attribute <code>"Rich Text AreaPress ALT-F10 for toolbar..."</code> that display a jqueryui tooltip all the time.</p>
  
  <p>I have tried to remove the title with js, but nothing changed:</p>
  
  <pre><code>document.getelementbyid('message_ifr').RemoveAttribute('title');
  </code></pre>
  
  <p>Is there a way to remove the title from tinymce or the jqueryui tooltip on the textarea?</p>
  
  <p>EDIT:</p>
  
  <p><strong>this is tinymce code:</strong></p>
  
  <pre><code>tinymce.init({
  
  mode : "exact",
  
  elements : "message,notes",
  
  plugins: "advlist autolink lists link image charmap hr anchor pagebreak code fullscreen table ",
  
  toolbar: "undo redo | styleselect | bold italic | alignleft aligncenter alignright alignjustify | bullist numlist outdent indent | link image table code fullscreen",
  
  menubar: false,
  
  statusbar: false,
  
  });
  </code></pre>
  
  <p><strong>and jquery-ui tooltip code:</strong></p>
  
  <pre><code>$(function() { 
      $( document ).tooltip({ 
      content: function() { return $(this).attr('title'); } // br
      }); 
  });
