The BaseController state is now constrained to valid JSON. Anything that can't be serialized (e.g. functions) or gets mutated during serialization (e.g. `undefined` gets converted to `null`) is disallowed. This should prevent an entire class of bugs resulting from unexpected changes when serializing state as JSON. For example, we serialize state when sending it over `postMessage`, and when persisting the state.
