Does that run in the content process? It sort of felt like this was meant to be funneled through [this bit that I linked earlier](https://searchfox.org/mozilla-central/rev/e6cb503ac22402421186e7488d4250cc1c5fecab/dom/events/EventStateManager.cpp#2264-2272), but that has no coverage, and I don't know if that means there's just no tests or if it's not the right bit or if there's some other way this is meant to make its way to the parent process?
