Enchanted tools may break without warning as durability bar no longer shows up.

What I expected to happen was the durability bar to appear and decrease as usual, even with unbreaking III on it

*What actually happened was the durability bar never showed up, and my gold pickaxe broke unexpectedly. This happens, i believe, on all pickaxes. I then enchanted an iron pickaxe and used it. It had unbreaking 3 on it, I used it a bit, and the durability did not appear at all. I then pressed F3 + h and saw that the durability did decrease.

Steps to Reproduce:
1. Enchant a pickaxe.
2. Mine something a few times.
3. The durability bar will never appear.
