Navigation after file share intent is not working

Description

If you want to navigate to another page when an intent is called (e.g. to share a pdf file to the MAUI app) the app only opens on the MainPage without any further navigation.

I hope the approach in the reproduction project is the one of the right ways since I have not found any documentation for working with intents in the MAUI context properly.

Steps to Reproduce

1. Create a File > New .NET MAUI app
2. Add to the MainActivity the Intent Filters Intent.ActionSend, Intent.ActionView to allow deep linking / opening our Maui app from a URL

[IntentFilter(
    new[] { Intent.ActionSend, Intent.ActionView },
    Categories = new[] { Intent.CategoryDefault },
    DataMimeType = @"application/pdf")]

4. Set LaunchMode = LaunchMode.SingleTop in Activity
5. Add a GoToAsync() call for another page in OnNewIntent()
6. Build and run the app
7. Open or share a pdf file from another app (e.g. my files app) to the MAUI app

Expected outcome: another page opens
Actual outcome: the MainPage is displayed

Start with the public NavigationAfterIntentBug reproduction project and inspect MainActivity, especially the OnNewIntent() handler and its GoToAsync() call. Reproduce the file-share or open-intent flow on Android 12, then trace why the app remains on MainPage. Done means the intended page opens after the intent is received.
