title: Draft js. Persist EditorContent to database
body: <p>I'm trying to persist <code>draft-js</code>'s <code>EditorContent</code> to database then read and recreate the EditorContent object again. 
  But <code>EditorContent.getPlainText()</code> strips away rich text content. I don't know how else to do it. </p>
  
  <p>How do I properly persist <code>EditorContent</code>?</p>
