passengers aren't spawning in

I'm trying to make a crafting recipe for making a chicken jockey, but the zombie isn't spawning
here's my code, if it helps
{
  "type": "minecraft:crafting_shapeless",
  "category": "misc",
  "ingredients": [
    "minecraft:zombie_spawn_egg",
    "minecraft:chicken_spawn_egg"
  ],
  "result": {
    "count": 1,
    "id": "minecraft:chicken_spawn_egg",
    "components": {
        "entity_data": {
            "id": "minecraft:chicken",
            "Passengers": [{"id": "minecraft:zombie", "IsBaby": true}]
        },
        "item_model": "minecraft:zombie_spawn_egg",
        "minecraft:enchantment_glint_override": true
    }
  }
}
