Description

Programmatically selecting an item in a CollectionView does not respect the VisualStateManager in its ItemTemplate (applied by styles or otherwise). Selecting the item as a user (tap / click) works.

Steps to Reproduce

1. Create a new MAUI app and replace default views with a CollectionView. Set its SelectionMode to "Single." Subscribe to its "Loaded" event. Add a VisualStateManager to its ItemTemplate that changes the BackgroundColor to Aqua when Selected.

2. Assign a list of strings to the CollectionView's ItemSource and, when its Loaded event fires, set the CollectionView's SelectedItem to the second string from the list.

3. On Windows: When the CollectionView loads, the second item is selected with the default selection style:

Clicking a different item correctly applies the custom selection style:

4. On iOS 17.0 simulator it's even worse. When the CollectionView loads and the second item is selected it just disappears:

Selecting a different item doesn't bring it back:

And when selecting a different item again, either the SelectionMode or VisualStateManager breaks, applying selection styles to multiple items:
