Эффект согласованной геометрии не работает с окном ⇐ IOS

[Гость]

I have a square that is embedded within a scroll view inside a subview. When the square is clicked I want to animate it to the top of the view hierarchy and present it above everything else using a matched geometry effect. I cannot get the animation to work. When the square presented at the top is dismissed it should animate back down to the original view.

Problem I present the square at the top of the view hierarchy through a window which makes the animation fail. How can I correctly animate with a window? How can I add basic match geometry effects, transitions, and other animations with windows?
