This issue has stayed since the item stack component was added in 24w12a, but I'm hoping it gets fixed soon.
When adding "is_meat" to the [minecraft:food] component, nothing changes. Trying to use the item on either a wolf or a tamed wolf to feed it doesn't work.
How to replicate:
Run the example command:
minecraft:stick[food={nutrition:1,saturation:1,is_meat:true}]Summon a wolf.
When trying to feed it, whether it be tamed or not, it is not fed the item.
