I don't like option 3. It's rather unlikely that's the app folks actually
want to go to in this case.

I don't think option 1 is a full solution either. KC_RESTART cookie may be
missing as you say, but it could also be overwritten by another client

Can't we do option 2 in the code that redirects to the next step in the
flow? That way it's always there. We should also add to action tokens so an
invalid action token page can also display a link back to the app.
