@Happypig375 This appears to be an issue specific to UWP in Xamarin.Forms 4.6. It works correctly on all other platforms, and it was working with Xamarin.Forms 4.5.

I reproduced it in C# (works with XF 4.5, doesn't in XF 4.6).

Repro-CSharp-BoxView-XF46.zip

I would recommend you transfer this issue to Xamarin.Forms.

Hmm. Seems to be fixed already: https://github.com/xamarin/Xamarin.Forms/pull/10540
