When replicating without a Periodic Snapshot task, Recursive is not working.

I set up a one-time replication task to copy one pool to another, selecting the pool itself as the source (i.e. replicate everything), and used Recursive.
Unfortunately, even though the auto snapshot was created, it was only created for the root dataset and none of the others, and thus an effectively-empty dataset was sent (I don't have anything in the root dataset).

I tried playing with the settings, but it doesn't seem to pick up on the recursive part at all.
