Adaptive Layouts iOS 27

I was experimenting with existing APIs using a NavigationSplitView and noticed that in the SwiftUI preview, resizing causes the component to switch between the content view and the sidebar.

However, with the new DeviceHub tool, the app doesn’t detect the new size and stays in the content view. Is this expected?

I would expect Navigation Split View to handle size changes automatically. Is this expected behaviour?
