Subtypes of /obj/item/stack/medical (for example, /obj/item/stack/medical/mesh) don't attempt to treat wounds when applied.
Reproduction:
Try to heal a mob that has a burn wound, such as /datum/wound/burn/flesh/moderate
If they have burn damage and a wound, only the damage is healed. If the limb only has a wound, it says [affecting.plaintext_zone] is not hurt! (code/game/objects/items/stacks/medical.dm: 158)
Tested on TG, confirmed not upstream.
