...largely by rewriting everything that takes place inside the queued task. Compared to the previous version, this one has a clearer if/otherwise branching structure, avoids any early returns, and makes it easier to follow when exactly the entry's document state's document is set to a non-null value and what impact that has.
This fixes a couple logic bugs where final steps were not getting applied quite correctly for all branches. Closes #9767.
@ADKaster can you take a look? @kalenikaliaksandr might also be interested.
