Inline edit row not work if class inherits other class

[Sonic3R]

I'm using latest version of Radzen: 4.1.12

@page "/fetchdata"
@inherits FetchDataBase
@using BlazorApp1.Shared

<PageTitle>Weather forecast</PageTitle>

<h1>Weather forecast</h1>

<p>This component demonstrates fetching data from the server.</p>

and

public class FetchDataBase : InlineComponentBase<WeatherForecast>
{
        private static readonly string[] Summaries = new[]
        {
                "Freezing", "Bracing", "Chilly", "Cool", "Mild", "Warm", "Balmy", "Hot", "Sweltering", "Scorching"
        };

        protected override WeatherForecast _selectedItem => new WeatherForecast();

        protected override Task LoadDataAsync()
        {
            _items = Enumerable.Range(1, 15).Select(index =>
            {
                var rand = Random.Shared.Next(-20, 55);

                return new WeatherForecast
                {
                    Date = DateTime.Now.AddDays(index),
                    TemperatureC = rand,
                    Temperature = rand.ToString(),
                    Summary = Summaries[Random.Shared.Next(Summaries.Length)]
                };
            }).ToList();

            return Task.CompletedTask;
        }

        protected override Task EditRow(WeatherForecast item)
        {
            _editForm.Model = item;
            return base.EditRow(item);
        }
}

and InlineComponentBase

public abstract class InlineComponentBase<TItem> : ComponentBase where TItem : class
{
        protected List<TItem> _items;
        protected EditForm _editForm;
        protected abstract TItem _selectedItem { get; }
        protected RadzenDataGrid<TItem> _grid;
        protected int _totalItems;
        protected int _page;
        protected readonly int _pageSize = 20;
        protected int _pageNumber = 1;
        protected bool _isLoading;

        protected abstract Task LoadDataAsync();

        protected virtual async Task LoadData(LoadDataArgs args)
        {
            _isLoading = true;

            try
            {
                await LoadDataAsync();
                _totalItems = _items.Count;
            }
            finally
            {
                _isLoading = false;
            }
        }

        protected virtual Task EditRow(TItem item)
        {
            return _grid.EditRow(item);
        }

        protected Task SaveRow(TItem item)
        {
            return _grid.UpdateRow(item);
        }

        protected void CancelEdit(TItem item)
        {
            _grid.CancelEditRow(item);
        }
}

The inline component abstract class I needed to re-use and force other component pages to follow structure.

I created repo here: https://github.com/Sonic3R/RadzenDataGrid to help you to reproduce issue

Repo issue:

1. Go to Fetch data page from left navigation sidebar
2. Click on pencil icon to get into edit mode
3. The EditRow method is called but nothing happened

If I put all codes from InlineComponentBase into FetchDataBase class (of course, without generic using) then edit works.

Do I do something wrong or it is a bug ?
