title: jsqmessageviewcontroller ios11 toolbar
body: <p>I have tried the swift example of <code>JSQMessageViewController</code> inside iOS 11 simulator. Here is the result:<a href="https://i.stack.imgur.com/dYraP.png" rel="noreferrer">screenshot</a></p>
  
  <p>I have tried using safe area margin and modify the toolbar constraint but there is still no difference. It seems that the toolbar is outside UIWindow (UITextEffectsWindow instead). Is there any solution?</p>
