steps to reproduce:
Use "minecraft:use_animation":"eat" in the resource file for a custom item.
Load the addon.
Attempt to eat your custom item.
Result:
No animation is played, after set time one item is removed from stack burp sound plays and hunger is filled by set amount.
Expected result:
Eat animation plays ending in consumption of item
Attached are the files for such an item
Can't tell if it's still happening because a new bug is preventing me from loading addons with custom items
