I believe I have had it not work - stealthy scouts attack a full province then the GR turn up later. But this was in a big confusing game & I may have got the orders wrong.
The solution is to have the scout next door & use a normal move to enter the province.

I know you can engage cloaking device to avoid the magic movement spells. It can be a real pain chasing stealthy flying raiders, though they may only attack every other turn.
