[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 #3 from Olli Pettay <bugs@pettay.fi> ---
...because different instances of MutationObserver may observe
different things.
One script library might observe only things X, and another one
things Y. those things shouldn't mix up.
