Server-side appears to be broken

I don't generally use it, but tested it for #85.

I get:

System.InvalidOperationException: JavaScript interop calls cannot be issued at this time. This is because the component is being statically rendererd. When prerendering is enabled, JavaScript interop calls can only be performed during the OnAfterRenderAsync lifecycle method.

It appears changing @(await Html.RenderComponentAsync<App>(RenderMode.ServerPrerendered)) to RenderMode.Server fixes this. But maybe there was a purpose in prerendering?
