[iOS] Using long-press navigation on back button using shell does not update the shell's current page

[Vetle444]

Description

First of all, thank you for the amazing framework you have built!

We are struggling with using the long-press navigation on the back button, here is what happens:
If one is using Shell and the NavigationStack is >1, you get a back button where you can long-press on it to show all the pages that is in the NavigationStack (except for the page you are at of course). If you select a page to navigate back to, the Shell's CurrentPage is not getting updated. This is causing problems in our published app.

Steps to Reproduce

1. Use the standard .NET MAUI sample.
2. Create a new ContentPage (TestPage.cs).
3. Create a button to navigate to it: _ = Shell.Current.Navigation.PushAsync(new TestPage());.
4. Tap and hold on the back button and release to navigate back.
5. Set a breakpoint in the page you navigated back to, for instance in OnAppearing.
6. Observe that the Shell.Current.CurrentPage property is still set to the page you navigated to before.

@PureWeen thoughts?

Also, another issue here is that we are relying on Shell's Navigated and Navigating events, and those aren't firing when using long-press.

I am having the same problem, please let me know if anyone has solved this problem.

Hello,

I'm also facing the same issue with latest version.

Issue : on iOS when long press on back button and navigating through the menu then not updating shell current page, as well as not notified to OnNavigating and OnNavigated and even did not get callback on OnBackButtonPressed.

Expected : at least it's calls OnBackButtonPressed when user using LongPress back button navigation.
maybe maui enhance it and provide a flag to disable long press back button. ref(#19793)
