Normal behaviour for the TCH. Remember in the normal ICE car, the engine is there to give a bit of push which makes the brakes less sensitive and the stop is smoother. If you tried to stop a normal ICE car in neutral there is the same grabby baheviour. Been there done that. You have to be real light on the brakes at the stop. If the ICE is running at the stop there is less of a problem than if the car is on E mode alone.
