    We will fix the problem in the next patch version.

    For now, you can try:

    [ExposeServices(typeof(MainSiderbarMenuItem))]
    [Dependency(ReplaceServices = true)]
    public partial class MyMainSiderbarMenuItem
    {
        protected override void OnInitialized()
        {
            ActivateCurrentPage(null);
        }
    
        protected virtual void OnMenuItemClick(MenuItemViewModel currentMenuItem)
        {
            ActivateCurrentPage(currentMenuItem);
        }
    
        protected override void ActivateCurrentPage()
        {
            return;
        }
    
        protected virtual void ActivateCurrentPage(MenuItemViewModel currentMenuItem)
        {
            var menuItem = currentMenuItem ?? MenuItem;
    
            if (menuItem.MenuItem.Url.IsNullOrEmpty())
            {
                return;
            }
    
            var menuItemPath = menuItem.MenuItem.Url.Replace("~/", string.Empty).Trim('/');
            var currentPagePath = new Uri(NavigationManager.Uri.TrimEnd('/')).AbsolutePath.Trim('/');
    
            if (menuItemPath.TrimEnd('/').Equals(currentPagePath, StringComparison.InvariantCultureIgnoreCase) || currentMenuItem != null)
            {
                Menu.Activate(menuItem);
            }
        }
    }
    
    @inherits Volo.Abp.AspNetCore.Components.Web.LeptonTheme.Components.ApplicationLayout.Navigation.MainSiderbarMenuItem
    
    @if (MenuItem.MenuItem.IsLeaf)
    {
        var url = MenuItem.MenuItem.Url == null? "#" : MenuItem.MenuItem.Url.TrimStart('/', '~');
    
        <li class="@(MenuItem.IsActive ? "current" : "") @MenuItem.MenuItem.CssClass" id="@MenuItem.MenuItem.ElementId">
            <a href="@url" target="@MenuItem.MenuItem.Target" @onclick="() => OnMenuItemClick(MenuItem)">
                <span class="lp-icon">
                    <i class="@(MenuItem.MenuItem.Icon ?? "")"></i>
                </span>
                <span class="lp-text">
                    @MenuItem.MenuItem.DisplayName
                </span>
            </a>
        </li>
    }
    else
    {
        <li class="@(MenuItem.IsActive ? "current" : "") has-drop">
            <a href="#" @onclick:preventDefault @onclick="ToggleMenu">
                <span class="lp-icon">
                    <i class="@(MenuItem.MenuItem.Icon ?? "")"></i>
                </span>
                <span class="lp-text">
                    @MenuItem.MenuItem.DisplayName
                </span>
                <span class="lp-arrow-icon" for="@MenuItem.MenuItem.ElementId">
                    <i class="fa fa-chevron-down"></i>
                </span>
            </a>
            <ul class="@MenuItem.MenuItem.CssClass" id="@MenuItem.MenuItem.ElementId" style="display:@(MenuItem.IsOpen || MenuItem.IsActive ? "block" : "none")">
                @foreach (var childMenuItem in MenuItem.Items)
                {
                    <MyMainSiderbarMenuItem Menu="@Menu" MenuItem="@childMenuItem"/>
                }
            </ul>
        </li>
    }
