Ian's suggestion seems fine to me. The language of the "clean up" stuff that
runs microtasks is:

"3. If the stack of script settings objects is now empty, perform a microtask
checkpoint."

It's the first part of that clause which causes the two different orderings.

I don't think there's any new bug here, just the same old one that WebIDL needs
to be invoking callbacks via HTML spec methods.
