Mermaid diagram throws a (syntax error in text - mermaid version 11.12.3) message for the mermaid diagram in the description

Perhaps my version of Markdown Viewer 4.0.1 does not support mermaid version 11.12.3...

Thanks for reporting this issue!

I could reproduce it and I also verified that this bug still appears on the current development state, which has Mermaid 11.15.0.

Apparently, something in Markdown Viewer's rendering engine doesn't like these <<enumeration>> statements. Removing them from all classes got the diagram to be rendered just fine.

The diagram does not only render correctly on https://mermaid.live/ but also via the Mermaid plugin for VS Code and on this very issue.

I hope to fix this with the next release.
