title: Buttons on toolbar do not work when app launch from background?
body: <p>I am facing a weird problem in my app. </p>
  
  <p>I have few buttons on toolbar when tapped presents a popovercontroller. If the app is taken to background (by pressing home button) while popover is visible, on relaunch from background buttons on the toolbar doesn't work. However if i touch somewhere in the popover or out side toolbar boundaries popover is dismissed and app work fine.</p>
