2 years ago What that paragraph is trying to say is that all targets of an explicit-root observer are defined by the spec as "same-origin-domain" targets. The relationship with the top-level origin is only relevant for implicit-root observers.
Feel free to fix this PR, or I will put up a separate one.
As discussed with @szager-chromium the other day, the sentence that I'm removing in this PR is incorrect. A target of an explicit root observer certainly does not have to be a same-origin-domain target, because you can provide an explicit root in cross-origin subframes, but in said subframes the target's setting's object's origin is of course cross-origin with that of the top-level one.
