  // Non-WebView versions of Chrome use the frame's last committed origin for
  // dialog attribution (crbug.com/1241497). However, WebView exposes JS dialog
  // calls to users, which means that a change to using the origin (exposed as
  // a URL) would be app-visible and a potential compatibility issue.
  //
  // In addition, WebView is special in that the "last committed origin" and the
  // origin of the "last committed URL" can be different due to a legacy app-
  // exposed setting, so such a change might be even more breaking.
  //
  // TODO(crbug.com/1241925): Figure out if some kind of migration can be done
  // here, as this is one of several instances in which moving from URL to
  // origin would be desirable.
