def to_absolute_uri
  # Via the W3 spec[1]: "If the a element has no href attribute, then
  # the element represents a placeholder for where a link might
  # otherwise have been placed, if it had been relevant, consisting of
  # just the element's contents."  So, we assume a link with no href
  # attribute (i.e. `uri == nil`) should be treated the same as an
  # intra-page link.
