This is your problem. That is an ancient version of Asciidoctor PDF with functionality that does not match the current docs. You should at least be using Asciidoctor PDF 1.5.3. If you upgrade, I think you will find that it works as expected.

p.s. I'm not sure why Ubuntu is holding back the upgrade of asciidoctor-pdf in the LTS release. The latest distro release included 1.5.3. If anyone has some sway there, I would appreciate it if you could make the case for the package being upgraded to a stable version.

I used the asciidoctor and asciidoctor-pdf packages that come with Ubuntu 20.04 LTS.
Anyway, I've now removed those packages and installed using gem and it all works great now.
