I can also reproduce this problem when I deploy the WhattoEat project using the Microsoft.Maui.Controls 9.0.90-ci.inflight.25314.2 with a light theme.

1. Deploy dotnet/maui-samples at whattoeat on iOS or Maccatalyst platforms.
2. Observe that the spaces of some of the pages has a black background color.

When you switch to dark theme, it displays properly:

This issue can also be reproduced with CollectionViewHandler2.
