Otherwise if the global object specified by settings is a WorkerGlobalScope, for each owner in the global object's owner set, if owner is a Document, append owner’s browsing context to related browsing contexts.

Consider the case where a Document A creates a Worker B, and Worker B creates another Worker C. Calling "get related browsing contexts" with C's settings object would return an empty set. Should it not return { A }?
