A small correction here which is mentioned only in the slides of previous
mail:
Actually, we have had the correct microtask handling since the beginning of
microtasks and it has been used with MutationObserver.
Another different mechanism also called microtask internally was added for
Promises, but it did something very different to the original one.
In bug 1193394, we are migrating the one used with Promise to the one used
with MutationObservers to to improve the conformance to HTML standard.
