Re-opening Modal Dialog with Grid having ObservableCollection DataSource throws ArgumentException error

[Dave]

Each time I open the modal dialog containing a Grid, I refresh the grid data. When I close and subsequently re-open the dialog I get the following error:

Uncaught Error Error: System.ArgumentException: There is no tracked object with id '3'. Perhaps the DotNetObjectReference instance was already disposed. (Parameter 'dotNetObjectId')

    at endInvokeDotNetFromJS (https://localhost:44333/_framework/blazor.server.js:1:3700)

    at <anonymous> (https://localhost:44333/_framework/blazor.server.js:1:72054)

    at _invokeClientMethod (https://localhost:44333/_framework/blazor.server.js:1:72040)

    at o.onmessage (https://localhost:44333/_framework/blazor.server.js:1:48819)

The following code reproduces the error (Blazor Server, DotNet 6.0):

<SfButton @onclick="OnSelect">Open Dialog</SfButton>

<SfDialog ShowCloseIcon="true" IsModal="true" @bind-Visible="@_visible">

    <DialogTemplates>

        <Content>

            <SfGrid DataSource="@Items" />

        </Content>

    </DialogTemplates>

</SfDialog>

@code

{

    private bool _visible;

    public ObservableCollection<ItemModel> Items { get; set; } = new();

    private void OnSelect(MouseEventArgs args)

    {

        UpdateItems();

        _visible = true;

    }

    protected void UpdateItems()

    {

        Items.Clear();

        Items.Add(new ItemModel {Name = "Item1"});

        Items.Add(new ItemModel {Name = "Item2"});

    }

    public class ItemModel

    {

        public string? Name { get; set; }

    }

}
