Does the fluent web component React wrapper work?

[logan2z]

I'm looking at building a component library based on Fluent but I'd like to create the library using Web Components and use the fluent React wrappers to expose a React-compatible version i.e. I'd like to single-source the library using WC but provide an easy way for React developers to use it.

I've tried the React wrapper examples provided by Microsoft and some found on blogs, but running them always results in the same error in every browser I've tried (Chrome, Firefox, Safari):

platform.js:80 Uncaught TypeError: Reflect.getPrototypeOf called on non-object
at Reflect.getPrototypeOf ()
at Object.getAccessors (platform.js:80:1)
at getElementKeys (index.js:57:1)
at ReactComponent.render (index.js:169:1)

at Object.invokeGuardedCallbackDev (react-dom.development.js:4213:1)
at invokeGuardedCallback (react-dom.development.js:4277:1)

Has anyone ever got these wrappers to actually work? If so, can anyone suggest what I might be doing wrong that is causing this error? FWIW, I'm running the Microsoft examples verbatim.
