The state object had been changed, but our mock states for tx approval were using the old keys.
Rather than try to muck about and figure out each and every change, I've re-generated a UI dev state for tx approval, which should help @zanibas on his current project.
We can continue adding new dev states as needed from here. If anyone catches a state that doesn't render correctly, it's worth checking if a new snapshot doesn't solve things.
Debugged by adding new debugging loggers, and I've left them in place for easier future debugging.
