title: Live copy text from TinyMCE to the hidden textarea it is connected to?
body: <p>The problem I'm experiencing with TinyMCE is that it keeps my hidden textarea (it becomes hidden as TinyMCE is inited) empty until the form it is in is submitted.</p>
  
  <p>I realize that it can be done with callbacks and stuff like that, but it would be overhead if there were a built-in way to do that, so I'm asking is there one?</p>
  
  <p>P.S. This is not a duplicate of <a href="https://stackoverflow.com/questions/15958140/tinymce-live-copy-text-from-tinymce-to-regular-text-field">this question</a> because it's been quite a big while since it was asked.</p>
