strictly speaking, this is a breaking change, because this method is accessible outside the js-sdk. But it's really not intended to be called anywhere except internally.

If we really want I could add a new onCryptoEventWithARealRoom method, use that from sync.ts etc, and deprecate the existing method. But it feels to me like that would be adding a bunch of dead code for very little gain.

const roomId = room.roomId;
const content = event.getContent<IRoomEncryption>();
