EXCEPTION: ApplicationRef.tick is called recursively

When I use external scripts, I have to run manually tick method to check for app changes.

For example facebook login:

FB.login(response => {
  // do some changes
  this.isLoggedIn = true;

  // required tick
  this.applicationRef.tick();
});

All works ok while I wait for the response callback to be executed.

But I get EXCEPTION: ApplicationRef.tick is called recursively when I do some actions before the response callback is executed. For example when I focus an input element or whatever that angular will check for changes.
