→ ❌ The same item appears as the output
This wasn't the case when repairing items was restricted to crafting tables and anvils.

The iron pick shown in the screenshot wasn't enchanted.
Anvils (the opposite of grindstones when it comes to enchanting), on the other hand, don't let you get an output until you either edit the name or put an item that can be "merged" with the first item in the second slot.
While some people might argue that it is because grindstones don't require XP but anvils do, I have a feeling that eventually, someone will discover a very abusable duplication glitch revolving around this bug, provided it doesn't get fixed.

When putting a diamond sword in the first slot, it temporarily wouldn't generate an output, though I assume that was lag.
Isn't this intended? It gets rid of enchantments
