bug: onActive not called in simulator

I don't have any real device that is supposed to support onActive/onInactive, so I can't test on real device, but in simulator (i.e: enduro3) in SDK 8.1.0 onActive is not called. Interestingly onInactive is called:

using Toybox.Application as App;
import Toybox.Lang;
import Toybox.System;

class MyApp extends App.AppBase {
	
	function initialize() {
		AppBase.initialize();
	}

	function onStart(state as Dictionary?) as Void {
		log("onStart");
	}

	function onActive(state as Dictionary or Null) as Void {
		log("onActive");
	}

	function onInactive(state as Dictionary or Null) as Void {
		log("onInactive");
	}

	function onStop(state) {
		log("onStop");
	}

    function log(msg as String) as Void {
        System.println(msg);
    }
}

onStart
onInactive
onStop
