SwiftUI - View within Sheet Displayed Incorrectly in iOS 17

In iOS 17, when I try to display a form inside a sheet, under certain conditions the section title and button label will have incorrect style.

Here's a minimal code that can reproduce the issue. The platform is iOS 17.0 (21A5303d)

import SwiftUI

struct TestView: View {
    var body: some View {
        List {
            RowView()
        }
    }
}

struct RowView: View {
    @State var showSheet = false
    
    var body: some View {
        VStack {
            Button("Show Sheet") {
                showSheet = true
            }
            .sheet(isPresented: $showSheet) {
                MySheet()
            }
        }
    }
}

struct MySheet: View {
    var body: some View {
        Form {
            Section {
                Text("Hello World!")
                
                Button {
                    // nothing
                } label: {
                    Label("Button", systemImage: "star")
                }
            } header: {
                Label("Section", systemImage: "star")
            }
        }
    }
}

#Preview {
    TestView()
}

When I tap the button Show Sheet, the sheet pops out as shown in the screenshot below:

There are 2 incorrect behavior found in this screenshot:

1. The section title should have a smaller font size and in gray color.
2. The button label's icon shouldn't be dimmed out.

For comparison, the correct result should look like the following screenshot:
