Nit: I think it's really weird that there's both `maxIntervalForUserGestureForwarding` in DOMTimer and `maximumIntervalForUserGestureForwarding` in XMLHttpRequest, and that they're different values. (1s vs. 10s.)

Doesn't this mean that a xhr -> timer -> xhr of less that 10s will break if the first xhr takes > 1s?

No, because XMLHttpRequest and DOMTimer both set a RefPtr<UserGestureIndicator> instance variable to null when their local timeout expires.
