I'd still suspect something bridging the switch. It would not need much.
Take the switch off then test it and see if it flashes.

I've seen this with these fangled electronic ballasts before.

Its normal on almost all installations. Wiring coupling allows small
amounts of charge to be picked up by 'isolated' wiring and eventually
there is enough charge in the reservoir capacitors to energise the unit
- for a tiny period.

Solution is a large value resistor across the live-neutral near the unit.
