Border Margin on IOS Increases Padding

[pschubert777]

Description

When increasing the margin for a element in IOS, it seems to instead increase the padding.

For example, when increasing the top and bottom margin from 10 to 40, the space within the border increases, but not the space between other elements in the CollectionView.

IOS- Margin 10

IOS - Margin 40

However, it works with Android

Steps to Reproduce

1. Create a File > New Maui App
2. Create an Observable collection in the MainPage.xaml.cs
3. Create a CollectionView and set the ItemSource to the Observable collection in the MainPage.xaml
4. In the DataTemplate, wrap each list item with a border, set the top and bottom margin equal to 10
5. Run the IOS emulator
6. Switch the top and bottom margin to 40
