The jumper mentioned would probably defeat the Local Control Sensor from turning the module on when the loads local switch was toggled from on to off and back on.
It will not defeat the actual sensing current from keeping sensitive loads like LEDs from glowing or pulsing.
The module also has a sensing circuit to determine if it is on or off. That circuit can not be defeated or it will pulse like a machine gun when you try to change its on or off status.
Now the latest ones could be different. X10WTI changed the appliance module to be more friendly to sensitive loads the socket may also have been updated.
The fix. Local Control frequently could be defeated. By putting an electrical cube tap on the outlet and putting a 7W incandescent night light and the normal load on the module. It normally would load down the sensing voltage so a sensitive load would not flash or pulse when off.
