[Android] Grid with custom MauiScrollview control and handler has wrong z index and changes when overscrolling

[jurganson]

Description

I have a grid with the row definitions "Auto, *". In the first row, I have a simple HorizontalStacklayout with some text, sort of like a banner. Then in the second row, I have a custom MauiScrollView control which is populated by a handler in Android. When running in iOS I see the expected result of the scrollview rendering inside its allocated space and essentially "slides under" the banner. However, in Android, the Scrollview is rendered on top of the banner. Furthermore, when I overscroll at the bottom of the list, the ZIndex changes and renders it below as it should, resulting in a wierd UI bug.

Steps to Reproduce

1. Create a MAUI sample app
2. In the main .xaml, create a Grid with RowDefinitions "Auto, *"
3. Create a simple TableView control
4. In Android, make a handler which populates the control inside a custom Android view which has been set by CreatePlatformView
5. In the aforementioned grid, add a label or other view to the first row and then the custom control to the second row.
