I am trying to implement LazyHGrid on tvOS 14 with a pinned header. If I use standard buttons as grid items, the items scroll properly by changing its focus. However if I use my own custom style for the buttons, the first item is hidden behind the pinned header. Here's a repro code:
struct ContentView: View {
		var rows: [GridItem] = [GridItem(.fixed(113))]
		@State private var selected : Bool = false
		@State private var isFocused : Bool = false
		
		var body: some View {
				VStack (alignment: .leading, spacing: 0) {
						ScrollView([.horizontal]) {
								LazyHGrid (rows: rows, alignment: .top, spacing: 10, pinnedViews: .sectionHeaders, content: {
										Section(header: HeaderView(title: "NBC").border(Color.white)){
												ForEach((0...20), id: \.self) {
														let codepoint = $0 + 0x1f600
														let codepointString = String(format: "%02X", codepoint)
																Button(action: { print("selected")}) {
																		CellView(title: "\(codepointString)")
																}
// Comment out this line - it will start working properly
																.buttonStyle(MyCustomButton())
												}
										}
						 })
					 }
				}
		}
}
struct HeaderView: View {
		@State var title : String
		
		var body: some View {
				VStack {
						Text(title).frame(width: 160)
				}
				.frame(maxWidth: .infinity, alignment: .topLeading)
				.frame(height: 113)
				.background(Color.blue)
		}
}
struct CellView : View {
		@Environment(\.isFocused) var isFocused: Bool
		@State var title : String
		
		var body: some View {
				VStack{
						Text(title).font(.headline)
						Text("Very intersting movie")
				}.padding()
				.background(isFocused ? Color.gray : Color.red)
		}
}
struct MyCustomButton: ButtonStyle {
		func makeBody(configuration: Self.Configuration) -> some View {
				configuration.label
						.frame(minWidth: 0, maxWidth: 300)
						.foregroundColor(.white)
						.background(configuration.isPressed ? Color.red : Color.green)
						
		}
}
