When changing the MainPage of the app while an animation view is on screen an InvalidOperationException is thrown. Details below.

Cannot assign a native control without an Element; Renderer unbound and/or disposed. Please consult Xamarin.Forms renderers for reference implementation of OnElementChanged.
