If you trade with a wandering trader for Ink Sacs, the Ink Sacs cannot be converted into black dye. They can, however, be used to craft things like black Shulker Boxes. Also, these Ink Sacs will not stack with regular Ink Sacs obtained from squids. (not shown in video)

Steps to reproduce:
Use spawn eggs to spawn in wandering traders until you get one that sells Ink Sacs

Use emeralds to obtain the ink sacs

Attempt to craft these ink sacs into black dye

Expected outcome: Ink Sacs should be able to be converted to black dye, even when obtained by trading with a wandering trader.
