Transposed array is not equal to its explicit equivalent

[stxue1]

When transpose is called on an array, it is not considered equal to its explicitly typed counterpart:

version 1.1

workflow wf {
  input {}
  Array[Array[Int]] a = [[1,2,3]]
  output {
    Array[Array[Int]] a_transposed = transpose(a)
    Array[Array[Int]] a_expected = [[1],[2],[3]]
    Boolean equal = a_transposed == a_expected
  }
}

{
  "dir": "/home/heaucques/Documents/wdl-conformance-tests/20240702_105206_wf",
  "outputs": {
    "wf.a_expected": [
      [
        1
      ],
      [
        2
      ],
      [
        3
      ]
    ],
    "wf.a_transposed": [
      [
        1
      ],
      [
        2
      ],
      [
        3
      ]
    ],
    "wf.equal": false
  }
}

The WDL 1.1 spec has a good example of this case as well implemented as part of their unit tests
