Current Behavior

Looks like there are some issues with the Popup in iOS with CommunityToolkit.Maui 6.0.0.

• Popup is no longer vertically centered. With net7.0 the popup is located in the top-left corner (image 1), with net8.0 the popup is centered horizontally, but the vertical alignment is incorrect (image 2). This worked fine in v5.3.0
• The background shadow is gone. This worked fine in v5.3.0
• Popup has a corner radius that cannot be adjusted (also an issue in v5.3.0)

Android seems to work just fine (image 3)

Expected Behavior

iOS popup rendering should match Android, which works.

Steps To Reproduce

1. Open and run solution from repro
2. Hit the button to show the popup
