Comment:
Fields with callable defaults use `show_hidden_initial` (renders a hidden
widget with initial value after the widget), that's why you need to pass
initial data to forms, e.g.
{{{
>>> data = {'modifications': '[]', 'initial-modifications': '[]'}
>>> form = VehicleForm(data, instance=vehicle)
>>> form.has_changed()
False
}}}
