[Bug 24810] "invoke MutationObserver object" should be updated for microtasks

https://www.w3.org/Bugs/Public/show_bug.cgi?id=24810

--- Comment #2 from Anne <annevk@annevk.nl> ---
I'm not sure I'm fully following the new world order.

http://dom.spec.whatwg.org/#concept-mo-invoke is all I have right now. It seems
the substeps of step 2 can be wrapped in a "execute a compound microtask
subtask" to do those steps. 

I guess each time a mutation record is added to a record queue I could check a
global flag to see if a compound microtask is already queued and if not, add a
compound microtask to the queue that'll invoke "concept-mo-invoke" and add a
step 4 to "concept-mo-invoke" to clear this new flag, but I'm not a 100% sure
that will do the right thing.
