Setting ProtectedCursor not working in RichEditBox

Describe the bug

The goal is to show a "hand" cursor when the user hovers over a link in my RichEditBox.
In UWP I was able to do this by subclassing RichEditBox and overriding OnPointerMoved

protected override void OnPointerMoved(PointerRoutedEventArgs e)
{
    base.OnPointerMoved(e);
    if (GetLinkAtPosition(e.GetCurrentPoint(this).Position) == null) { return; }
    Window.Current.CoreWindow.PointerCursor = new CoreCursor(CoreCursorType.Hand, 1);
}

Steps to reproduce the bug

According to this answer, on WinUI3 I need to use ProtectedCursor. However, this code does not work, the "IBeam" cursor persists:

protected override void OnPointerMoved(PointerRoutedEventArgs e)
{
    base.OnPointerMoved(e);
    if (GetLinkAtPosition(e.GetCurrentPoint(this).Position) == null) { return; }
    ProtectedCursor = InputSystemCursor.Create(InputSystemCursorShape.Hand);
}

Start with the RichEditBox subclass and its OnPointerMoved handler shown in the issue, using Windows App SDK 1.8 Experimental 2 on the stated Windows 11 version to reproduce the persistent IBeam cursor. Investigate the ProtectedCursor behavior for link hover and verify that the cursor changes to Hand over links without changing unrelated RichEditBox pointer behavior.
