Comment 2 for bug 1390098

This is most probably some focus/app-active issue within the shell, as described by boiko:

> So, here is the thing: when a call is accepted (the snap decision action
> is clicked), telephony-service requests that dialer-app is launched,
> which is ok.
> But when the dialer is already launched and in foreground something
> weird happens:
> - when the snap decision appears, dialer-app's application activeness is
> set to false (which is correct, since the snap decision is in foreground)
> - when the action is clicked, dialer-app's activeness switches to true,
> then to false briefly and then to true again. My guess is that this
> happens because telephony-service is requesting dialer to be opened.
