[regression/8.0.0-preview.3.8149] - modal to modal doesnt call OnNavigatedTo

[Zack-G-I-T]

Description

When you are on a modal page and navigate to another modal page using Shell.Current.GoToAsync, the OnNavigatedTo method is called on the first modal page - but never on the second.

Steps to Reproduce

1. Download project
2. Add breakpoints to all OnNavigatedTo methods
3. Run app and click buttons to go to each page - see that the breakpoints never get hit.

@XamlTest if you look at the class you are breaking on - it is the same one each time. "TestModalPage.xaml.cs". It never hits the "TestModalPage2.xaml.cs" OnNavigatedTo.
Why would it hit the OnNavigatedTo method on the first page when you are going away from it?

Confirmed that this regressed between 8.0.0-preview.2.7871 and 8.0.0-preview.3.8149. #13025 seems sus. Note that in preview 2, the NavigatedTo event fires for Modal1 every time, but it also fires the event for the modal on top.

Yes, you are right, thanks for reminder. It never hits the "TestModalPage2.xaml.cs" OnNavigatedTo.
