The previous PR had a side effect that I knew about but did not adjust
the tests to account for: doc.json will always be pushed up after some
change happened to the package, including seeing it again because of
repeating the sequence number.

You might argue that this is a bug. But if you don't argue that way,
adjusted the test that accounts for it.
