I'm trying to move to current versions of asciidoctor & related plugins, and our spec generation is now giving warnings of the form

> asciidoctor: WARNING: problem encountered in image: /tmp/Vulkan-Docs/images/pipelinemesh.svg; Unknown tag 'flowRoot'; ignoring

Running asciidoctor with -v --trace doesn't deliver any more information so I'm unclear where in the pipeline the problem is happening, or if it even is something we should be concerned about. For reference the old / new versions of gems used are:

asciidoctor 1.5.8 / 2.0.10
asciidoctor-diagram 1.5.12 / 2.0.1
asciidoctor-mathematical 0.2.2 / 0.3.1
asciidoctor-pdf 1.5.0.alpha.16 / 1.5.3

Any ideas on tracking this down further? It does not occur during HTML generation, so something about how SVGs are incorporated into PDF generation would appear to be responsible.
