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

https://www.w3.org/Bugs/Public/show_bug.cgi?id=20131

--- Comment #11 from Olli Pettay <bugs@pettay.fi> ---
My inconsistency argument came from comment 6.
if A isn't expecting oldValue and B is and there are two
records, one with oldValue, one without.
The one without oldValue would be shared, the other one wouldn't.
