title: TinyMCE 4 Issues on IE 11
body: <p>I have recently updated some admin systems on websites to use TinyMCE 4, using the JS version.
  I have just discovered a bug that only occurs in IE11, which is the following:</p>
  
  <p>When a Textarea loads it contains the posted html data, but then after the split second it takes for TinyMCE to trigger, all the content within the Textarea is hidden - and TinyMCE is just empty.</p>
  
  <p>It seems to work on all other browsers, including other versions of Internet Explorer. Has anyone else had this issue and know of a solution?</p>
  
  <p>Cheers</p>
