Auto Tape Style monitoring doesn't work with no time selection in Time Selection Auto Punch Mode

If there is no time selection active, punching in manually during playback in Time Selection Auto Punch mode with Auto Tape Style Monitoring turned on does not result in the expected behaviour. The track media AND the monitored input are played simultaneously, while in regular record mode only the monitored media is played (correct behaviour).
