ListView Fails to Remove Multiple Items with RemoveRange Operation in Bound Collection

[prakashKannanSf3972]

Describe the bug

In a ListView with a bound Collection, the RemoveRange operation does not remove multiple items as intended. Instead of deleting the specified range of items (e.g., from index 0 to 4), only a single item is removed. This issue disrupts the functionality of bulk removal operations in ListView collections.

Steps to reproduce the bug

• Run the attached sample application - ListViewTestSample.zip.

• Click the "Remove" button in the view.

• Observe that the ListView does not remove the specified range of items.

Expected behavior

Upon clicking the "Remove" button:

• Five items (indices 0 through 4) should be removed from the collection.

• The ListView should update accordingly to reflect the removal of these five items simultaneously.

It works for me (Windows 10 22H2, Windows App SDK 1.6.241114003)
if I do instead :
OnCollectionChanged(new NotifyCollectionChangedEventArgs(NotifyCollectionChangedAction.Reset));
