Demo app to demonstrate layout issues

App Layout

1st page: nothing special

2nd page:

• contains a Grid with 3 columns
• the 3rd column's width is set to 0 and can be programmatically updated
• the 3rd column contains a CollectionView

1. Android+Windows

Issue:

• CollectionView items don't appear correctly

Repro steps:

• Windows (Windows 11) or Android (API 36)
• Open the 3 column page
• Tap the 1st button to add 1 or more items
• Tap the 2nd button to display the 3rd column with the CollectionView

Result:

• No item appears. You have to scroll down to see the 1st item.

Expected:

• All items appears directly.

2. Android

Issue:

• Navigation bar is under the top edge of the screen (under the notch)

Repro steps:

• Windows (Windows 11) or Android (API 36)

Result:

• Navigation bar is under the top edge of the screen (under the notch)

Expected:

• Navigation bar is below the notch, as SafeAreaEdges equals All for both the ContentPage and the Grid.

3. iOS (issue in progress)
