ListView GroupHeader background color not rendering correctly on iOS

[hbraasch]

Description

A simple supplied reproduction demonstrates the issue. On iOS, a listview with headers always displays the header with a white background colour. In the reproduction the page background color is set to black, the listview background color (as well as the component (a label) added to the views) is set to be transparent. BUT, the header background always remains white. This is how the reproduction displays on Android (correct):

This is how it renders on iOS:

Steps to Reproduce

1. Open the reproduction from github [https://github.com/hbraasch/ListViewColorTester.git] in Visual Studio
2. Run the app for Android and iOS
3. Observe the differences

This is still an issue as of .NET MAUI 8.0.6. Will this ever be addressed?
