[Android] SafeAreaEdges break with tab navigation and Shell.TabBarIsVisible="False"

[FinnKr]

Description

When using a TabBar with 2 tabs as ShellContent and navigating between them breaks the SafeAreaEdges=All on Android if one page has Shell.TabBarIsVisible="False".

Steps to Reproduce

1. Create a .NET MAUI App with a TabBar navigation and 2 pages
2. Use SafeAreaEdges="All" on both pages
3. Disable the TabBar on the first page
4. Navigate to the second page using a button/programmatically
5. Go back to the first page using the TabBar
6. Repeat 2-3 times

Expected result:
Page 1 respects all SafeAreas all the time

Actual result:
Page 1 pushes its content behind the bottom SafeArea after 2 navigations

Android

Affected platform versions

Did you find any workaround?

Calling OnPropertyChanged for SafeAreaEdges will recalculate the SafeArea and "fix" the representation.
For example in OnSizeAllocated:

protected override void OnSizeAllocated(double width, double height)
{
	base.OnSizeAllocated(width, height);
	
	OnPropertyChanged(nameof(SafeAreaEdges));
}
