OnUpdate does not fire in InCell edit mode for decimal fields

Reproducible below, expected results is that after editing the decimal field you'll get the data under the grid. Actual: either it does not get updated, or the value is always 0.

@using Telerik.Blazor.Components.Grid
 
 
<TelerikGrid Data=@MyData EditMode="incell" Pageable="true" Height="500px">
    <TelerikGridEvents>
        <EventsManager OnUpdate="@UpdateHandler" OnEdit="@EditHandler" OnDelete="@DeleteHandler" OnCreate="@CreateHandler"></EventsManager>
    </TelerikGridEvents>
    <TelerikGridToolBar>
        <TelerikGridCommandButton Command="Add" Icon="add">Add Employee</TelerikGridCommandButton>
    </TelerikGridToolBar>
    <TelerikGridColumns>
        <TelerikGridColumn Field=@nameof(SampleData.ID) Title="ID" Editable="false" />
        <TelerikGridColumn Field=@nameof(SampleData.Name) Title="Name" />
        <TelerikGridColumn Field=@nameof(SampleData.SomeDecimal) Title="Some Decimal" />
        <TelerikGridCommandColumn>
            <TelerikGridCommandButton Command="Delete" Icon="delete">Delete</TelerikGridCommandButton>
            <TelerikGridCommandButton Command="Save" Icon="save" ShowInEdit="true">Update</TelerikGridCommandButton>
        </TelerikGridCommandColumn>
    </TelerikGridColumns>
</TelerikGrid>
 
@lastUpdateOnDecimal
 
@code {
    public void EditHandler(GridCommandEventArgs args)
    {
        SampleData item = (SampleData)args.Item;
 
        Console.WriteLine("Edit event is fired for column " + args.Field);
    }
 
    string lastUpdateOnDecimal;
 
    public void UpdateHandler(GridCommandEventArgs args)
    {
        string fieldName = args.Field;
        object newVal = args.Value; //you can cast this, if necessary, according to your model
 
        SampleData item = (SampleData)args.Item;//you can also use the entire model
 
        //perform actual data source operation here
 
        //if you have a context added through an @inject statement, you could call its SaveChanges() method
        //myContext.SaveChanges();
 
        if (fieldName == "SomeDecimal")
        {
            lastUpdateOnDecimal = $"decimal for {item.ID} updated to {newVal} on {DateTime.Now}";
        }
 
        var matchingItem = MyData.FirstOrDefault(c => c.ID == item.ID);
        if (matchingItem != null)
        {
            matchingItem.Name = item.Name;
        }
 
        Console.WriteLine("Update event is fired for " + args.Field + " with value " + args.Value);
    }
 
    public void CreateHandler(GridCommandEventArgs args)
    {
        SampleData item = (SampleData)args.Item;
 
        //perform actual data source operation here
 
        item.ID = MyData.Count;
        MyData.Add(item);
 
        Console.WriteLine("Create event is fired.");
    }
 
    public void DeleteHandler(GridCommandEventArgs args)
    {
        SampleData item = (SampleData)args.Item;
 
        //perform actual data source operation here
 
        //if you have a context added through an @inject statement, you could call its SaveChanges() method
        //myContext.SaveChanges();
 
        MyData.Remove(item);
 
        Console.WriteLine("Delete event is fired.");
    }
 
    //in a real case, keep the models in dedicated locations, this is just an easy to copy and see example
    public class SampleData
    {
        public int ID { get; set; }
        public string Name { get; set; }
        public decimal SomeDecimal { get; set; }
    }
 
    public List<SampleData> MyData { get; set; }
 
    protected override void OnInit()
    {
        MyData = new List<SampleData>();
 
        for (int i = 0; i < 50; i++)
        {
            MyData.Add(new SampleData()
            {
                ID = i,
                Name = "Name " + i.ToString(),
                SomeDecimal = i
            });
        }
    }
}
