In a simple app with a ScrollView inside a NavigationView, on scroll the content of the scrollView doesn't smoothly transition from its size with navigationBarDisplayMode .large to .inline, but rather makes this a jarring jump.
Minimum code to reproduce:
The following code produces the desired smooth transition though:
I could not replicate the issue using UIKit's UITableViewController inside a UINavigationViewController, nor with a UIScrollView inside a UINavigationViewController.

Minimum code to reproduce:
Code Block swift struct ContentView: View { var body: some View { NavigationView { ScrollView { ForEach(0..<200, id: \.self) { i in Text("Row \(i)") .frame(maxWidth: .infinity) } } .navigationTitle("Test") } } }
