I crafted a new bow and was NOT able to reproduce my original issue (i.e. crafting the Dispenser worked as expected).
Then, I enchanted/disenchanted the same bow (NBT tag(s): 2), and encountered the "Dispenser -> Dropper" phenomenon. So, it does seem to be issue MC-129057 (The recipe book doesn't move ingredients that have NBT data).
Sorry for not finding the duplicate... i only queried for Status != Resolved.
