Attempting to run a function tag with optional entries that contain macros with /function ignores all functions

Functions with macros break the rest of the chain even if ‘required' is set to false.

Below are the files used in the demonstration:

File: tag1.json

{
	"values": [
	{
      "id": "datapack:function1",
      "required": false
  },
	{
      "id": "datapack:function2",
      "required": false
  }
	]
}

File: :function1.mcfunction

$give @a $(item)

File: function2.mcfunction

say function2 is successful

The results are attached below.
