I think it's a little weird that we use "this" here, but it's probably okay.

This mirrors what we did in HTML (e.g. https://html.spec.whatwg.org/multipage/browsers.html#the-origin-interface:extract-an-origin and https://html.spec.whatwg.org/multipage/webappapis.html#windoworworkerglobalscope-mixin:extract-an-origin). We could replace it with something like "the object's" throughout if that would be preferable?
