Um. Good thing you looked. I doubt we want to revert that change now.

ISTM the actual problem here is that we're reverting to IDLE state too
soon. I didn't try to trace down exactly where that's happening, but
I notice that in the non-pipeline case we don't go to IDLE till we've
seen 'Z' (Sync). Something in the pipeline logic must be jumping the
gun on that state transition.
