I'm pretty sure its equipment because villagers traded it to me so if I crafted it, it would be items
Steps to Reproduce:
get money
find farmer villager
trade money for pumpkin pie.
Hover over Pumpkin Pie in inventory
Observed behavior
Shows category of "Equipment"
Expected behavior
Category should be "Items"
Edit: it happens on Bread and Cake (I'm not sure if it actually happens on Cake this is just memory because I have no proof of remembering)
Pumpkin pie, bread, and cake are in the Equipment section of the creative inventory, under the "Miscellaneous Foods", next to the "Cooked Foods." There are no foods in "Items."
Please make sure you can reproduce issues before making a report.
