title: Aria on fixed element
body: <p>I'm trying to make an app that renders in a webkit better to use with screen readers. It's mostly working well the only issue is the menu bar that appears at the bottom of the screen is not working correctly. When the app is scrolled to the top it works fine. BUt when it's scrolled down the box that appears around the button when tapped appears above the button. The box moves more the more the page is scrolled and double tapping does not activate it. Is there a way to tell the screen reader the element is in a fixed position?</p>
  
  <p>Thanks for the help!</p>
