Remarks
When an element has CanBeScrollAnchor set to true, the framework locates the first IScrollAnchorProvider in that element's chain of ancestors and automatically calls its RegisterAnchorCandidate method. This occurs both when the property is set on an existing element or an element is added to the live tree with the property already set.
Similarly, when the property is set to false (or an element is removed from the visual tree with the property set to true), the framework calls the UnregisterAnchorCandidate on the first IScrollAnchorProvider.
