If SplitView is combined with SemantiZoom and GridView, the swaying will emerging in all windows size, and that's my real problem

I think this issue is more suited for the WinUI repository: https://github.com/microsoft/microsoft-ui-xaml

What should i do ? Fire a issue in https://github.com/microsoft/microsoft-ui-xaml?
But my app does not use microsoft-ui-xaml , is it appropriate to fire a issue?
What about the third gif? The XAMLControls Gallery app also has this issue!
