[MC-248824] Loot table entry of type "dynamic" copies list reference rather than deep copying items

When using /loot replace ... to transfer the contents of a shulker box to another container (e.g. a chest) using this loot table (see below), the item list REFERENCE is transferred rather than the list contents being deep-copied. This results in a pair of "entangled" containers where removing any of the items from either container will result in the respective item being removed from the other.

minecraft/loot_tables/blocks/shulker_box.json:

{
  "type": "block",
  "pools": [
    {
      "rolls": 1,
      "entries": [
        { 
          "type": "dynamic", 
          "name": "contents"
        }
      ]
    }
  ]
}

Setup:

Create a world (a flat world will do)
Download this datapack and enable it in the world (it only contains the loot table in question)
Place down a shulker box and a chest
Place items inside the shulker box
Run this command: /loot replace block <CHEST coords> container.0 27 mine <SHULKER BOX coords>
See that the contents of the shulker box seem to have been copied to the chest.

Observations:

When taking any items out of either the chest or the shulker box, the respective item will be removed from the other container, too
When destroying the chest (dropping all the items onto the ground), all the transferred items will no longer be in the shulker box
Putting items in either of the containers does not transfer them to the other, and they will not be deleted when either of the blocks is destroyed
