We still see the issue or a similar one as from bug 29504 on the batch checkout of items with $3 and CircConfirmItemParts:
1. Set a staff member with circ permissions, but not FORCE_CHECKOUT
2. Turn on: CircConfirmItemParts, BatchCheckouts, BatchCheckoutsValidCategories (all)
3. Log in as staff member in step 1
4. Attempt to checkout an item with a 952$3 from the batch checkout tab
5. The button to process/confirm the checkouts is missing.
