Documentation Feedback

Checking the implementation, I observe that the FocusMonitor emits inside NgZone:

And confirmed checking NgZone.isInAngularZone() in a subscription.

But documentations says:

Note: currently the FocusMonitor emits on the observable outside of the Angular zone. Therefore, if you markForCheck in the subscription you must put yourself back in the Angular zone.
