ClusterAggregates.razor often fails unless I add a delay

I'm a newbie so please excuse any mistakes I have made by submitting this issue. I have not used Slack before, and I was unable to join the group there. My email address is mark@markevans.org if anyone needs to add me first.

I have found that the example file ClusterAggregates.razor often fails. It's inconsistent. The map always loads. But sometimes the bubble layer loads and sometimes it doesn't. When it fails, I get the following JS error:

atlas.min.js:55 Error: layers.75e0ea40-700e-4382-9741-5b7027861563: source "2671a15c-0192-4d19-b5e6-bdffc9c45ef8" not found

at t.addLayer (atlas.min.js:105:172826)
at fN._addMapboxLayers (atlas.min.js:105:1048190)

I have also found that adding the following delay fixes the problem:

public async Task OnMapReady(MapEventArgs eventArgs)
{
    await eventArgs.Map.AddPopupAsync(_popup);        

    _datasource = new AzureMapsControl.Components.Data.DataSource
        {
            EventActivationFlags = AzureMapsControl.Components.Data.DataSourceEventActivationFlags.None(),
            Options = new()
            {
                Cluster = true,
                ClusterRadius = 50,
                ClusterProperties = new Dictionary<string, AzureMapsControl.Components.Atlas.Expression>(_entityTypes.Select(entityType => BuildClusterProperty(entityType)))
            }
        };

    await Task.Delay(100); // ############# map often fails without this delay ###############
    await eventArgs.Map.AddSourceAsync(_datasource);        
}

I'm wondering if there is a better way to avoid this issue?

To Reproduce

Create a new Blazor Web app.
Add all the nuget packages, links to js files, appconfig.json stuff, AuthService.cs, data file etc.
Copy/paste ClusterAggregates.razor to your project.
Run

Expected behavior Load the bubble layer every time rather than just some of the time.
