Start by reproducing the issue on Android with .NET MAUI 10.0.70, comparing SafeAreaEdges.None on ContentPage and AbsoluteLayout with the behavior from 10.0.30. Trace the SafeAreaEdges handling to identify why None matches Container; done means None renders fullscreen while Container retains its existing behavior.
