loot table of an armorstand

How can I make it so if an armorstand has arms, if it gets destroyed he keeps the ShowArms Tag. I changed the armorstand loot table in the minecraft folder in my datapack and it drops 2 armorstands both without the show arms tag: my loottable:
{
  "type": "minecraft:entity",
  "pools": [
    {
      "rolls": 1,
      "bonus_rolls": 0,
      "entries": [
        {
          "type": "minecraft:item",
          "name": "minecraft:armor_stand",
          "functions": [
            {
              "function": "minecraft:copy_components",
              "source": "this",
              "include": [
                "minecraft:entity_data"
              ]
            }
          ]
        }
      ]
    }
  ]
}
