Trying to mix item modifier references and inline values in a list prevents the pack from loading

The bug

Previously, a loot table could apply a list of item modifiers, with some declared inline and some being references:

{
  "pools": [
    {
      "rolls": 1,
      "entries": [
        {
          "type": "item",
          "name": "apple",
          "functions": [
            {
              "function": "set_count",
              "count": 5
            },
            {
              "function": "reference",
              "name": "test:whatever"
            }
          ]
        }
      ]
    }
  ]
}

The new syntax would look like this:

{
  "pools": [
    {
      "rolls": 1,
      "entries": [
        {
          "type": "item",
          "name": "apple",
          "modifier": [
            {
              "type": "set_count",
              "count": 5
            },
            "test:whatever"
          ]
        }
      ]
    }
  ]
}

However, this does not work. This prevents the world from loading, and causes /reload to fail. The following error is logged:
