title: Sencha Touch - menu and edge swipes errors
body: <p>I'm wondering if anyone has found a fix for the issue, when the menu is initialized but has not been shown yet and the user makes edge swipes what leads to ST throwing errors:
  Uncaught TypeError: Cannot read property 'on' of undefined.</p>
  
  <p>Please see here what I mean (open console and make edge swipes):
