NavigationSplitView's sidebarToggle button temporarily disappear when showing sidebar

Hello!

I have a simple macOS, targeting macOS 13.0, which displays a NavigationSplitView with a sidebar and a detail. The sidebar toggle button works as expected, except when the sidebar is hidden and I press it to show the sidebar. It disappears temporarily and causes some glitches in the view.

I've tried switching columnVisibility values, navigationSplitViewStyle values, assembling List in different ways, to no avail. I have experience in SwiftUI, but not with Lists or NavigationLinks for that matter, I use navigation in a different way, but I'd like to stick with this solution. Unfortunately, I can't exactly figure out what's causing this behavior.

This is the code I've written so far.

import SwiftUI

@main
struct SomeApp: App
{
    var body: some Scene
    {
        WindowGroup 
        {
            MainScreen()
                .frame(minHeight: 450)
                .frame(width: 720)
                .presentedWindowToolbarStyle(.unified)
                .navigationTitle("SomeApp")
        }
        .windowResizability(.contentSize)
    }
}

enum MenuItem: Identifiable, Hashable
{
    case readme
    case about
    
    var id: String
    {
        title
    }
    
    var title: String
    {
        switch self
        {
            case .readme: "Readme"
            case .about: "About"
        }
    }
    
    var symbolName: String
    {
        switch self
        {
            case .readme: "newspaper.circle.fill"
            case .about: "info.circle.fill"
        }
    }
}

struct MainScreen: View
{
    @State var menuItems: [MenuItem]
    @State var selectedMenuItem: MenuItem
    
    init()
    {
        selectedMenuItem = .readme
        menuItems = [
            .readme,
            .about
        ]
    }
  
    var body: some View
    {
        NavigationSplitView
        {
            List(
                menuItems,
                selection: $selectedMenuItem
            ) { item in
                NavigationLink(
                    destination: {
                        switch selectedMenuItem 
                        {
                            case .readme:
                                Text("Readme")
                            
                            case .about:
                                Text("About")
                        }
                    },
                    label: {
                        HStack

                                .resizable()
                                .frame(

                                )
                                .foregroundStyle(
