Modal route issue - route runs twice when returning from second modal containing route outlet

This is most evident in iOS. I've set up a demo app:

https://stackblitz.com/edit/nativescript-stackblitz-templates-vwcmqt

In iOS, if you follow the steps (they're numbered) you'll see that when you navigate back on step five, the animation runs twice—backwards then forwards. This appears to come from the shouldDetach method NSRouteReuseStrategy. If I use the previous code for shouldDetatch that was altered here:

https://github.com/NativeScript/angular/commit/bebcde23c4d6a392638c23ec1e2bc63b06a9b43e

then it works without problem.

NOTE: For this demo, I've used 14.2.6-alpha.0 because without it, I can't use modals with ModalDialogParams because of injector scope issues. However, this router problem described above also occurs in 14.2.5 when the modal corrections are in place. Either way, something isn't working as it should.

Beginne mit der Methode NSRouteReuseStrategy.shouldDetach und vergleiche sie mit der früheren Implementierung im Commit beb cde23c4d6a392638c23ec1e2bc63b06a9b43e. Reproduziere den nummerierten Ablauf in der verlinkten StackBlitz-Demo auf iOS, einschließlich der Rückkehr aus dem zweiten Modal, das einen route outlet enthält. Als abgeschlossen gilt die Aufgabe, wenn die Zurücknavigation in Schritt fünf ihre Animation einmal statt rückwärts und vorwärts ausführt.
