def changed?(_record, _attribute)
  # With Active Storage we assume the record is always changed because
  # there is currently no way to know if the attribute has actually
  # changed.
  #
  # Calling record.changed? will not also work because it is not marked
  # as dirty in case the Active Storage attachment has changed.
  #
  # NOTE:
  # This should be changed in the future as the `attachment_changes` was
  # introduced to Rails by this commit:
  # https://github.com/rails/rails/commit/e8682c5bf051517b0b265e446aa1a7eccfd47bf7
  #
  # However, it is still not available in Rails 5.2.x.
