title: TinyMCE pastes to editor twice on Ctrl + V
body: <p>Using the jQuery version, everything works as expected except when anything is pasted into the editor, it pastes double what I expect.</p>
  
  <p>Init script:</p>
  
  <pre><code>$('textarea.editor').tinymce({
      theme : "modern",
      menubar : false,
      plugins: [
          "paste advlist autolink lists link charmap print preview anchor",
          "searchreplace visualblocks code",
          "contextmenu paste"
      ],
      paste_auto_cleanup_on_paste : true,
      paste_remove_styles: true,
      paste_remove_styles_if_webkit: true,
      paste_strip_class_attributes: "all",
  });
  </code></pre>
