Infinite Loop during Chat Widget Initialization

I'm trying to integrate Live Chat into our Angular app, but keep on getting an Range Error.

Unhandled Promise rejection: Maximum call stack size exceeded ; Zone: <root> ; Task: null ; Value: RangeError: Maximum call stack size exceeded

The code is a simple wrapper around the Live Chat Angular Chat Widget. Component:

@Component({
  selector: 'app-livechat',
  templateUrl: './live-chat.component.html',
})
export class LiveChatComponent {
  private liveChatApi: LiveChatWidgetApiModel;

  constructor() {}

  setApi(api: LiveChatWidgetApiModel) {
    this.liveChatApi = api;
  }
}

Template:

<livechat-widget (onChatLoaded)="setApi($event)" licenseId="xxxxxxx"></livechat-widget>

Full Stacktrace:
