      Creating two iframes that mimics the attention screen behavior on the
      device:
        - the 'dialer' iframe is the attention screen you have when a call is
          in place. it is a green bar, so we copy it as green here too
        - the 'apps' iframe mimics another application that is being run, be it
          dialer, sms, ..., anything that the user might want to trigger during
          a call
      The bug we intent to reproduce here is that in this case, if the user taps
      onto the top of the 'apps', the event fluffing code will in fact redirect
      the event to the 'dialer' iframe. In practice, this is bug 921928 where
      during a call the user wants to place a second call, and while typing the
      phone number, wants to tap onto the 'delete' key to erase a digit, but ends
      tapping and activating the dialer.
