add test for shadowroots falling back to global scope

Following discussions with the WCCG it was deemed undesirable that Scoped Custom Element Registries fall back to the global registry if undefined. If scoped registries desire such a behaviour they can collect the definitions from the global registry and apply them to the local registry.

This test fails in Chrome because it defines the alternate behaviour where the registry does fall back. Scoped registries are a prototype feature without a spec and so this feels like a good feedback channel for the WCCG to validate their desires and the interpretations of the explainer.
