Build result in web components being registered multiple times #793

I am using api-console build -t "RAML 1.0" ./api.raml -o ./build/api/reference to build my documentation.
It very recently broke. Without anything changing in our build process.

The browser crash with this error:

Uncaught DOMException: Failed to execute 'define' on 'CustomElementRegistry': the name "api-request-editor" has already been used with this registry
