This event is NOT sent if the view becomes transparent (or the reverse), it's ONLY linked with View.Show() and View.Hide(). For reference, a view is only shown if the view and its parents (up to the root view) are also visible, they are not transparent, and the view has a non-zero size. So if its parent is not visible, the view is not shown even though VisibilityChangedEventArgs.Type is SELF and VisibilityChangedEventArgs.Visibility is true.
