Item_changes not capturing booleans

[tjchambers]

In my tests I can see that booleans are not captured in PaperTrail item_changes.

  action: nil,
  changes: %{informed?: false},
  errors: [],
  data: #Sct.Align.Participant<>,

in examining the tests in this repo the person_test.exs seems to also replicate that regarding the gender column:

  assert Map.drop(person, [:company]) == %{
      company_id: target_company.id,
      first_name: "Isaac",
      visit_count: 10,
      birthdate: ~D[1992-04-01], #  this is the only problem
      last_name: "Nakri",
      gender: true
    }

    assert Map.drop(version, [:id]) == %{
      event: "update",
      item_type: "Person",
      item_id: first_person.id,
      item_changes: %{
        first_name: "Isaac",
        visit_count: 10,
        birthdate: ~D[1992-04-01],
        company_id: target_company.id
      },
      origin: "user:1",
      originator_id: nil,
      meta: %{
        linkname: "izelnakri"
      }
    }
  end

is there a reason for not capturing those in item changes?
