Somewhat twisted (but valid) layout of types can crash WASM:
Microsoft.AspNetCore.Components.WebAssembly.Rendering.WebAssemblyRenderer[100]
Unhandled exception rendering component: The type initializer for 'NestedStatic' threw an exception.
System.TypeInitializationException: The type initializer for 'NestedStatic' threw an exception.
---> System.TypeInitializationException: The type initializer for 'BlzWasmTypeInitRepro.TwistedType' threw an exception.
---> System.ArgumentNullException: Value cannot be null. (Parameter 'source')

This runs fine on server. Replacing the field at line 5 with a method can make the problem go away (which I used as a work around for my actual project) but that is not the point for this repo.
