This has already been reported : The ShouldConstrainToRootBounds property of the Popup doesn't work

[zhuxb711]

@castorix #5958 said that is a bug in WinUI3, also exists in UWP WinUI 2.7

@llongley is there a technical limitation for why this doesn't work today?

[llongley]

A very quick test app shows that it seems to work:

@zhuxb711 do you have a test app demonstrating the issue you're seeing?
