Review Comment:
Seems like this was probably copied from `isInStandbyState()`? But I don't
think it's right. If we can't find a state, we assume `STANDBY` state. If we
assume `STANDBY` state because a valid state could not be found, then
`isInObserverState()` should be false. So I think we should just `return false`
here.
