Classification:Bug Reproducible:Yes
SwiftUI’s “listRowBackground” function influences the row height when running in macOS, but does not for iOS.

1. Make a SwiftUI app containing a List object
2. Add a tall row to the List, using multiple Text objects in a VStack
3. Observe that the row height is calculated correctly
4. Add “listRowBackground(Color.yellow)” to the row
5. Observe that the row height is correct for iOS, but incorrect for macOS

struct ContentView: View {
	var body: some View {
		List {
			VStack(alignment: .leading) {
				Text("Here's to the crazy ones.")
				Text("The rebels.")
				Text("The troublemakers.")
				Text("The round pegs in the square holes.")
			.listRowBackground(Color.yellow) // comment out to get the correct row height

struct ContentView_Previews: PreviewProvider {
	static var previews: some View {
			.previewLayout(.fixed(width: 400, height: 400))
