Greetings and thank you for the hard work that has gone into Radzen Components.

We have a UI that is rendered using Interactive Server mode. Very intemittently (0.6% of the time) according to our automated tests we get the following exception:

System.ArgumentException: There is no event handler associated with this event. EventId: '2061'. (Parameter 'eventHandlerId')
   at Microsoft.AspNetCore.Components.RenderTree.Renderer.DispatchEventAsync(UInt64 eventHandlerId, EventFieldInfo fieldInfo, EventArgs eventArgs, Boolean waitForQuiescence)
   at InvokeStub_WebRendererInteropMethods.DispatchEventAsync(Object, Span`1)

This happens when Playwright enters some numeric values in a component that does the following:

RenderFragment ParameterComponent(Parameter parameter) => builder => 
{
	builder.OpenComponent<RadzenNumeric<double?>>(0);
    builder.AddAttribute(1, "oninput", EventCallback.Factory.Create<ChangeEventArgs>(this, (args) => OnChange(parameter, args.Value)));
}

Any idea why this Exception is thrown?

I'm not familiar with this error, I see it for the first time, however I've found this:
