12876	"Required ""type"" attribute is missing in the <style> element generated by the editor"	Jan Pechanec		"Type is required attribute of <style> tag according to http://www.w3.org/TR/html401/present/styles.html#style-group

But CKEDITOR generates following

{{{<style>.cke{visibility:hidden;}</style>}}}

There shall be simple fix - add attribute "" type='text/css' "" to generated <style> tag.
We tried to fix downloaded source code by adding one line into document.js:
{{{
  var style = new CKEDITOR.dom.element( 'style', this );
  style.setAttribute('type','text/css'); //added by us
  style.append( new CKEDITOR.dom.text( cssStyleText, this ) );
}}}
But it seems it does not work in Internet Explorer 11.
