When I am on Article Doc page, left navigation is not expanded

[FuadEfendi]

See this page:

Left navigation "doc-nav" supposed to be expanded (and it was before); but now something broken, maybe after recent upgrade; it worked fine before upgrade

Expanded:

Collapsed:

Left side should be expanded at article 3.1

Please provide a minimal reproducible repo, since it works as expected on the docs site, e.g. https://hbstack.dev/docs/content/markdown-syntax/

Thank you Razon so I compared with working site: issue happened after I added canonifyURLs: true to hugo.yaml.
So, I removed it, it works now. I was trying to implement "canonical" meta tag which is not in hbstack. It works now.
