Change pointer cursor when hovering over map elements

My UWP application contains a map with several POI. I am trying to change the mouse cursor from an arrow to a hand when hovering over specific poi to indicate its clickable.

This would change the cursor as soon as it enters the map still, as a simple test, I added a PointerEntered event for the mapcontrol and within it I have the following to change the cursor:

 Window.Current.CoreWindow.PointerCursor = new Windows.UI.Core.CoreCursor(Windows.UI.Core.CoreCursorType.Hand, 0);

It appears though the cursor does change however immediately gets overridden back to the pointer cursor.

Edit: Just realised When a poi is clicked (i.e. is selected) the cursor changes to a hand even when not over the map control until the poi is unselected. No good as I would like the cursor to change dynamically when hovering over a poi and revert back to cursor when moved away.
