Details

So, [1] alerts true, and [2] alerts false. Heycam says that he updated the spec in [3] so that instanceof should be scope-agnostic. This is kind of unexpected, since I'd imagine that these two cases would look the same under the hood: we should end up in the compartment of the constructor, with the object being a cross-compartment wrapper.

Wait, why? There is no sandbox here...
Oh, I see. The key is having the RHS be a proxy of any kind.... I guess we tested it for cases when the _LHS_ was the proxy, but not the other. Funtimes.
(In reply to Boris Zbarsky (:bz) from comment #3) > Oh, I see. The key is having the RHS be a proxy of any kind Well, a function proxy.
