So if I understand correctly, we used to have the exact same values for those tags twice with newer versions of Asciidoctor, but starting with the change we have one "empty" set of tags and one set of tags that contain the replaced values. And because Asciidoctor ignores the latter the end result is that we have empty ref info. > Post-a38edab7c8, we don't provide these attributes and Asciidoctor > inserts empty-ish values.
