+++ This bug was initially created as a clone of Bug #19554 +++

Currently, URL.createObjectURL is specified to work with autoRevoke set to
true, which allows Blob URLs to be valid past a provided stable state.

But stable state is not a sufficient concept, nor is the misdirected Bug 17988
which seeks to have microtask defined as a concept.

What is needed here is: something that's always invoked when exiting the
outermost script (including from parser-invoked script) .  If this is provided
in HTML5, we can use it to describe autoRevoke semantics.  This is useful for
the createObjectURL default pattern, which avoids persisting string-based
references to in-memory objects, minimizing leaks.
