Notes to Inheritors

If you override this method, always call the base implementation. The default base implementation performs some internal maintenance of reverse-inherited property state. Failing to call the base implementation will invalidate this state.

This method overrides OnVisualParentChanged(DependencyObject). FrameworkElement and Window both also override the UIElement3D implementation of OnVisualParentChanged(DependencyObject), and Window seals it.
