LiveQuery stop working when InAppBrowser is launched?

[magickaito]

I want to continue monitor events using ParseLiveQuery even if an InAppBrowser is launched. But I couldn't.

I noticed all events from Parse server appears to be paused/suspended, when an InAppBrowser is launched.

Here is a simplified code to demonstrate the problem:

export interface PageInterface {
  title: string;
  name: string;
  component: any;
  icon: string;
  logsOut?: boolean;
  index?: number;
  tabName?: string;
  tabComponent?: any;
}    
@Component({
  templateUrl: 'app.template.html'
})
export class ConferenceApp {
  @ViewChild(Nav) nav: Nav;
  appPages: PageInterface[] = [...];
  loggedInPages: PageInterface[] = [...];
  rootPage: any;
  browser: any;

  constructor(
    public events: Events,
    public userData: UserData,
    public menu: MenuController,
    public platform: Platform,
    public confData: ConferenceData,
    public parseData: ParseData,
    public storage: Storage,
    public splashScreen: SplashScreen,
    private iab: InAppBrowser
  ) {

    this.rootPage = TabsPage;
    this.platformReady();

  }

  listenToParse(){
    this.parseData.subscribe().then(
      (subscription)=> {
        subscription.on('open', () => {
          console.log('subscription opened');
        });
        subscription.on('update', (object:any) => {
          console.log('object updated');
        });
      },
      (error)=>{
        console.log(error);
      }
    );
  }

  openPage(page: PageInterface) {
    ...
  }


  enableMenu(loggedIn: boolean) {
    this.menu.enable(loggedIn, 'loggedInMenu');
    this.menu.enable(!loggedIn, 'loggedOutMenu');
  }

  platformReady() {
    // Call any initial plugins when ready
    this.platform.ready().then(() => {
      this.splashScreen.hide();

      this.listenToParse();
      
      setTimeout(() => {
        console.log("time out fired, launch iab!");
        this.browser = this.iab.create("https://www.google.com","_blank");
      },60000);

    });
  }

  isActive(page: PageInterface) {
    ...
  }
}

In the demo code above, we listen to changes of data from Parse server. It works until the InAppBrowser is launched, 60 seconds later. This is the log output:

//InAppBrowser launched. 

No more object updated event after InAppBrowser launched. Why?
