Customizing ports in Blazor.Diagrams not working?

[bstensrud72]

I have created my own port file MyCustomPort.razor like this just for testing:

@using Blazor.Diagrams.Core.Models
<span>Hello</span>
@code {
  [Parameter] public PortModel Port { get; set; } = null!;
}

And register it to the Diagram like this:

Diagram.RegisterComponent<PortModel, MyCustomPort>(true);

But when I inspect the port div it is empty. Is it not possible to override port rendering?
