The ejection seat is a rocket device. If it's connected to the avionics in any way, that is another potential point of failure. Maybe, if the cockpit canopy is jettisoned rather than fragmented at the moment the seat is fired, the switch/action of jettisoning the canopy is connected with avionics. Seems more likely but still improbable. But we need an expert...
