Having a suspicious stew in inventory prevents all types of suspicious stew from going into your inventory when milking brown mooshroom

The bug

When you have a suspicious stew in your inventory, you won’t get a suspicious stew into your inventory in creative mode. That is because MC-188352 was fixed. However this suspicious stew prevents all types from going into your inventory when milking. So if you for example have a suspicious stew with the wither effect in your inventory, you can’t get suspicious stews with other effects.

h3How to reproduce

1. Don’t have a suspicious stew in your inventory
2. Summon a brown mooshroom using this command: /summon minecraft:mooshroom ~ ~ ~ {Type:"brown"}
3. Feed it a wither rose
4. Milk it with a bowl
   → You will get a suspicious stew
5. Feed it a different flower, for example a dandelion
6. Milk it again with the bowl
   → You won’t get the suspicious stew, even though the stew that you have is a different type and gives a different effect.

Expected behavior: You can get the suspicious stew, because it would give a different effect.
