Меню навигации иногда не может быть закрыто в MudBlazor

Я изучаю и пытаюсь использовать MudBlazor для разработки своего веб-сайта. Но когда я добавляю свою пользовательскую страницу (все еще используя пути к страницам в MudTemplate), меню навигации невозможно закрыть. На некоторых сайтах он может быть закрыт. Когда я пытаюсь отладить функцию, которая устанавливает значение параметра, определяющего открытие и закрытие меню навигации, как DrawerToggle, на некоторых страницах это работает, на некоторых страницах - нет. Я провел весь день, пытаясь найти ответ, но безуспешно. Что я должен делать?

Вот мой MainLayout:

@using MUDTEMPLATE.Components
@using MUDTEMPLATE.DBData
@inherits LayoutComponentBase
@inject IConfiguration config

<MudThemeProvider @rendermode = "InteractiveServer" />
<MudDialogProvider @rendermode = "InteractiveServer" />
<MudSnackbarProvider @rendermode = "InteractiveServer" />
<MudLayout>
    <MudAppBar Elevation = "0">
        <MudIconButton Icon = "@Icons.Material.Filled.Menu" Color = "Color.Inherit" Edge = "Edge.Start" OnClick = "@((e) => DrawerToggle())" />
        <MudSpacer />
        <MudIconButton Icon = "@Icons.Material.Filled.MoreVert" Color = "Color.Inherit" Target = "_blank" />
    </MudAppBar>
    <MudDrawer @bind-Open = "_drawerOpen" Elevation = "1" Variant = "DrawerVariant.Temporary">
        <MudDrawerHeader>
            <MudText Typo = "Typo.h6">DATAVIET - MART</MudText>
        </MudDrawerHeader>
        <NavMenu />
    </MudDrawer>
    <MudMainContent>
        <MudContainer MaxWidth = "MaxWidth.ExtraExtraLarge" Class = "my-1 pt-1">
            @Body
        </MudContainer>
    </MudMainContent>
</MudLayout>
<div id = "blazor-error-ui">
    An unhandled error has occurred.
    <a href = "" class = "reload">Reload</a>
    <a class = "dismiss">🗙</a>
</div>
@code {
    bool _drawerOpen = true;
    protected override Task OnInitializedAsync()
    {
        DB.Set_Connect(config.GetConnectionString("DefaultConnection"));
        return base.OnInitializedAsync();
    }

    void DrawerToggle()
    {
        _drawerOpen = !_drawerOpen;
    }
}

Вот мое NavMenu:

@implements IDisposable
@inject NavigationManager NavigationManager
<MudNavMenu>
    <AuthorizeView>
        <Authorized>
            <MudNavGroup Title = "System" Icon = "@Icons.Material.Filled.Dashboard" Expanded = "true">
                <MudNavLink Href = "/Account/Register" Icon = "@Icons.Material.Filled.PeopleAlt">Register</MudNavLink>
            <MudNavLink Href = "counter" Match = "NavLinkMatch.Prefix" Icon = "@Icons.Material.Filled.List">Counter</MudNavLink>
            <MudNavLink Href = "weather" Match = "NavLinkMatch.Prefix" Icon = "@Icons.Material.Filled.List">Weather</MudNavLink>
            <MudNavLink Href = "Account/Manage" Match = "NavLinkMatch.Prefix" Icon = "@Icons.Material.Filled.List">@context.User.Identity?.Name</MudNavLink>
            <div class = "nav-item px-3">
                <form action = "Account/Logout" method = "post">
                    <AntiforgeryToken />
                    <input type = "hidden" name = "ReturnUrl" value = "" />
                    <button type = "submit" class = "nav-link">
                        <span class = "bi bi-arrow-bar-left-nav-menu" aria-hidden = "true"></span> Logout
                    </button>
                </form>
            </div>
        </Authorized>
        <NotAuthorized>
            @* <MudNavLink Href = "Account/Register" Match = "NavLinkMatch.Prefix" Icon = "@Icons.Material.Filled.List">Register</MudNavLink> *@
            <MudNavLink Href = "Account/Login" Match = "NavLinkMatch.Prefix" Icon = "@Icons.Material.Filled.List">Login</MudNavLink>
        </NotAuthorized>
    </AuthorizeView>
</MudNavMenu>
@code {
    private string? currentUrl;

    protected override void OnInitialized()
    {
        currentUrl = NavigationManager.ToBaseRelativePath(NavigationManager.Uri);
        NavigationManager.LocationChanged += OnLocationChanged;
    }

    private void OnLocationChanged(object? sender, LocationChangedEventArgs e)
    {
        currentUrl = NavigationManager.ToBaseRelativePath(e.Location);
        StateHasChanged();
    }

    public void Dispose()
    {
        NavigationManager.LocationChanged -= OnLocationChanged;
    }
}

Вот моя страница счетчика (здесь работает навигационное меню):

@page "/counter"

@using Microsoft.AspNetCore.Authorization

@attribute [Authorize]

<PageTitle>Counter</PageTitle>
<MudText Typo = "Typo.h3" GutterBottom = "true">Counter</MudText>
<MudText Class = "mb-4">Current count: @currentCount</MudText>
<MudButton Color = "Color.Primary" Variant = "Variant.Filled" @onclick = "IncrementCount">Click me</MudButton>
    @code {
    private int currentCount = 0;

    private void IncrementCount()
    {
        currentCount++;
    }
}

Вот моя страница регистрации (навигационное меню не работает):

@page "/Account/Register"

@using System.ComponentModel.DataAnnotations
@using System.Text
@using System.Text.Encodings.Web
@using Microsoft.AspNetCore.Identity
@using Microsoft.AspNetCore.WebUtilities

@inject IUserStore<ApplicationUser> UserStore
@inject SignInManager<ApplicationUser> SignInManager

@inject IdentityRedirectManager RedirectManager

<PageTitle>Register</PageTitle>
