Is there a resolution to that that has been posted anywhere?
Not so much, though it does seem that there is more support for your position on it than not. I am firmly opposed, saying that Characters and Enhancements activated in battle, if prevented, do not suddenly activate later in the battle. You get in infinite loops otherwise, and questions on activation if several 'ongoing' abilities suddenly all trigger at the same time because they were prevented when entering.
There is no reason that I see for cards that activate once to be able to reactivate if their prevention is negated. Cards like forts, sites, arts, and TC characters
in territory activate constantly, so they would simply activate now that the prevention is over. Cards like Enhancements and Characters only activate one time, and if they are prevented, they should not reactivate.
