GroupHeaderTemplate and GroupFooterTemplate Not Displaying in CollectionView(CV2)

[NafeelaNazhir]

Description

In CollectionView2, the GroupHeaderTemplate and GroupFooterTemplate are not displayed when IsGrouped is set to true and a GroupedList is assigned as the ItemsSource. The expected behavior is that the group header and footer should be visible when templates are set, but they do not appear.
