[BUG] Android hardware back button causes app to go to background when pressed on a TabbedPage inside a NavigationPage

[mdartu]

Description

This is a follow-up from my comment on #3123. I feel the fix associated with that issue improves the situation somewhat, but does not resolve it. The problem appears when navigating back to a TabbedPage inside a NavigationPage, while first having navigated away from the TabbedPage. The navigation works as expected when using the "soft" back button as presented by the NavigationPage. The app is sent to the background when using the hardware back button in that case.

I have modified the PrismMauiDemo app in the e2e folder to further demonstrate this, see STR below.

Steps to Reproduce

This is a modified version of the PrismMauiDemo app (based on commit 7be5a56) that can navigate to /NavigationPage/TabbedPage?createTab=ViewA

PrismMauiDemo-modified.zip

1. Hit "Tabbed Page inside Navigation Page button", this navigates to ViewA
2. Hit "ViewB" button, this navigates to ViewB.
3. Press the hardware back button, this will cause the app to be sent to the background. Pressing the "soft" back button does not, it navigates back to ViewA (which is the expected behaviour).
