Steps to reproduce:
While in Survival mode, enter the Crafting Table interface.
Search or seek the Dispenser item from the recipe book.
Click on it to auto-populate the Dispenser recipe into the 9x9 crafting grid...
However, the Dropper recipe populates and a Dropper item will be crafted (a Bow in your inventory is not placed into the 9x9 grid and is not consumed).
Clicking on the Dispenser item multiple times will not increment the number of Droppers created (even if multiple materials needed are present in the player inventory), but you can click the Dispenser and then the Dropper from the recipe book to create two Droppers.

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.
Resolved as a duplicate of MC-129057.
