Came across this while looking for a way to resolve the error: 
````
Uncaught DOMException: Failed to execute 'define' on 'CustomElementRegistry': the name "..." has already been used with this registry
````

In an SPA components get loaded and unloaded all the time. It is very surprising that this `CustomElementRegistry` is a one way call with no way to `undefine` or `unRegister` a component when needed.
