The other thing required is an addition to
http://www.whatwg.org/specs/web-apps/current-work/#processing-model-2
(between steps 3 & 4, probably) to deliver MutationRecords at the end
of every task (if there's anything there). This handles cases, such as
editing, where DOM is mutated without any script execution.
