Android HandleOnBackPressed not triggered on .NET MAUI 10.0.40 onwards

[ManuLin]

Description

We have a .NET MAUI / Blazor hybrid application and use a custom OnBackPressedCallback to handle back navigation via the hardware button, as suggested by Google. This solution used to work up to .NET MAUI version 10.0.31. From version 10.0.40 onwards, the "HandleOnBackPressed" method of the callback is not invoked anymore except on the very root page. I am not sure if this might be related to #33825

We are registering the callback in the "OnCreate" method of the Android MainActivity, as described here https://developer.android.com/reference/androidx/activity/OnBackPressedDispatcher.

Any help in this regard is greatly appreciated. For the moment, we will stay with version 10.0.31 to keep the navigation working.

Best regards,

Manuel
