I think this bug is only partially fixed. An incoming call is not silenced by tapping the power button, however the screen goes dark first and users don't know if the call continues "ringing". Switching the screen off gives the impression that the call was declined.
The desired solution is: press the power button and silence/mute call. Second press: screen goes dark.
