[Bug 20131] [MutationObservers] Unclear whether unique record instances are required in 5.3.2 "Queuing a mutation record"

--- Comment #17 from Rafael Weinstein <rafaelw@chromium.org> ---
I see. Thank you for clarifying. Yes, in that case in WebKit (and the original
spec), the record(withoutOldValue) is delivered to A and B.

So your concern is that developers attempt to rely on records either always or
never being shared?
