[Bug] Scroll breaks for ScrollView (or works on some tiny part of it) in nested grid after ScrollView translation by Y

Description

We have a grid with two elements: another grid with scrollview and any view, Both pushed to bottom. When we try to translate by Y both scrollview and second view from root grid - scroll for scrollview doesnt work or works on some tiny part of scrollview. If we don't use nested grid then scrollview scrolls.

Steps to Reproduce

From description, plus we have a codebehind for button which translates views (scrollView and x:Name="_button" button) by Y further to bottom and back. When views translation changed to 60 by Y - scroll doesnt work or works on some tiny part of scrollview.

Xaml for nested grid:
