Thanks for reporting

I can see it locally and in prod.

Looks like a temporary mermaid bug that was fixed in a newer release

Will be fixed by upgrading the deps on our own website (#11066), and that should work too on third-party Docusaurus sites. Let me know if the upgrade doesn't fix it for your site.
