ListBox filter not updating after drop

Hi
When filtering a listbox, then moving a item by dragging it to another listbox, and then trying to change the filter, a bug occurs : the filtered elements doesn't appear back.
Step to reproduce:
- filter "listbox-2" with, for example, "1"
- move item "Element n°10" to "listbox-1" (it will not work because of the unset scope)
- remove the filter of "listbox-2" (nothing happens, elements 2, 3, 4, 5, ... doesn't appear back)
Code:

   
               TItem="Element"
               TValue="int[]"
               DataSource="@Elements1"
               AllowDragAndDrop="true"
               Height="100%">
       
   
   
               TItem="Element"
               TValue="int[]"
               DataSource="@Elements2"
               AllowDragAndDrop="true"
               AllowFiltering="true"
               FilterType="Syncfusion.Blazor.DropDowns.FilterType.Contains"
               Height="100%">
       
   

@code {
    public class Element
    {
        public int Id { get; set; }
        public string Name { get; set; }
    }

    public List Elements1 = new();
    public List Elements2 = Enumerable.Range(1, 15).Select(v => new Element { Id = v, Name = "Element n°" + v }).ToList();

    protected override void OnAfterRender(bool firstRender)
    {
        base.OnAfterRender(firstRender);
        if (firstRender) StateHasChanged(); // Re-render component to update the ListBox component Scope references in each connected ListBox.
    }
}

I can't submit my edit, so I post a new message as the code didn't show as I wanted... (Please make a "code" block in your forum editor...................)

Hi


I've updated the Syncfusion package, but the issue isn't fixed

Hi Thiken,  
  
We are deeply regret for the inconvenience caused.   
  
We have fixed this issue and ensured all testcases. So, we are unable to move this fix into previous patch release. We have created a custom patch for the reported query and the same can be downloaded below link.  
  
  
Hence, we are working on that with high priority, and we have planned to move this our upcoming patch release which will be scheduled on end of July 27th, 2021.  
  
So, we suggest following below steps then upgrade our Syncfusion custom packages.  
      
      
  1. Due to the old Browser/NuGet cache.  
  2. https://blazor.syncfusion.com/documentation/common/how-to/upgrade-syncfusion-components-to-latest-version/#cache-problem 
  3. Outdated custom scripts referred in the application.  
      
Also, could you please ensure the problem after clearing the browser/NuGet cache or run the application using incognito window of the browser.      
  
Regards,  
Gayathri K
