Bot Framework Channel Emulator has invalid channel ID?

I'm using the C# Bot Framework library to retrieve some data from the Bot State Service. Whenever channelId == "emulator" in the code below, it fails with a 400 Bad Request. It looks like both Emulator versions 3.0.0.59 and 3.5.27 use this channel ID. Here's the returned payload:

{
  "error": {
    "code": "BadArgument",
    "message": "Invalid channel ID"
  }
}

Note that if I change channelId to something else like "skype", it works as expected.

var credentials = new MicrosoftAppCredentials(id, password);
this.botState = new BotState(new StateClient(credentials));
var channelId = activity.ChannelId;
await botState.GetUserDataAsync(channelId, activity.From.Id);

Received this answer from the Bot Framework team:

For emulator they need to use the activity’s serviceurl when create the state client. Builder automatically does that in the connector client factory:

https://github.com/Microsoft/BotBuilder/blob/master/CSharp/Library/Microsoft.Bot.Builder/ConnectorEx/IConnectorClientFactory.cs#L86

if (IsEmulator(this.address))
{
    // for emulator we should use serviceUri of the emulator for storage
    return new StateClient(this.serviceUri, this.credentials);
}

That error is from state.botframework.com (which is the default endpoint for stateclient) since emulator is not a valid channelid for the state service.
