MC-112198Natural mob equipment is not randomly damaged when swapped with another item
The bug
When a mob wearing randomly-generated armor is killed and the armor drops, it is given a random damage value. However, when a mob chooses to swap its spawn armor for a better piece of dropped armor, the original piece is dropped fully repaired instead of getting randomly damaged.
How to reproduce
Simply drop a piece of better (e.g. diamond) equipment next to a mob that is both wearing natural equipment and can pick up loot. It will replace its item and drop it fully repaired. If the mob were to be killed instead, the damage value would be randomized.
Example command (turn mobGriefing on and drop a diamond chestplate at this zombie's feet):
/summon zombie ~ ~ ~ {ArmorItems:[{},{},{id:leather_chestplate,Count:1b},{}],ArmorDropChances:[0f,0f,0.99f,0f],CanPickUpLoot:1b}
Note that the damage is not caused by damaging the mob. The random damage is applied on death and is not changed over the lifetime of the mob.
Random Armchair
To fix, maybe random mob equipment can just be pre-damaged from the beginning? That way, you won't have to update the item every possible way it can drop, and also won't need a special case anymore for 2.0 drop chance to leave damage untouched.

Why would you expect it to be randomly damaged if you gave the entity the item fully repaired?

I've also noticed that sometimes the original loot isn't dropped at all, but I can't find a way to reproduce that specifically.

Natural mob equipment is not randomly damaged when swapped with another item
Structured the report a little bit and removed the part describing MC-112198.

Right-clicking onto an adult zombie variant with a spawn egg will always spawn baby zombie without equipment or items regardless of type of zombie it is.
Steps to Reproduce
- Set difficulty to Hard
- Spawn a zombie, husk, zombie villager, or drowned
- Use the respective spawn eggs on the spawned entities
Expected & Observed Behavior
→ 
All of the baby zombies do not randomly spawn with random loot (armor, swords, shovels or as a chicken jockey for all variants, and tridents, fishing rods or natilus shells for baby drowned).
→ 
Just as the adult variants of the mobs, the zombies would spawn with randomized loot occasionally.

That happens because the armor / hand drop chances are used in this case as well, which is very likely intended.
Ah, that makes sense. For a while I've thought that wasn't the case, and was confused at the seeming "exploit" of throwing a mob a better item just so you can kill it and get both 100%.
Glad to see my anxious suspicion that I never tested was false, hahaha.
