Writing to target with asterisk * does not work

[TobiasNx]

add_field("animals[].*.test", "test")
copy_field("C", "animals[].*.C")
set_array("amimals[].*.testArray[]")

results:

{
  "animals" : [ {
    "A" : [ {
      "name" : "Jake"
    } ],
    "B" : [ "First" ]
  }, {
    "A" : [ {
      "name" : "Blacky"
    } ],
    "B" : [ "Second" ]
  } ],
  "C" : "test_2",
  "amimals[].*.testArray" : [ ]
}

expected:

{
	"animals": [
		{
			"A": [{"name":"Jake"}],
			"B": ["First"],
            "test": "test",
            "C": "test_2",
            "testArray": []

		},
		{
			"A": [{"name":"Blacky"}],
			"B": ["Second"],
            "test": "test",
            "C": "test_2",
            "testArray": []
		}
	],
	"C": "test_2"
}
