 My test authority was asleep for an hour, and so it didn't have a recent
 consensus. It started voting at 10:30 for round commit 3/reveal 3, but the
 rest of the network wasn't voting for commit 3/reveal 3 until 11.

 How does an authority recover from this situation if it has thrown away
 its state at 1030?

 Do we fix this by implemeting #19045 (keep voting for shared random
 values)?
 Or does that make this worse?
