website: broken references

[guillaumemichel]

Some pages such as https://specs.ipfs.tech/http-gateways/path-gateway/ (version: bafybeif4c3qwbay2po72qqqb3jagtnix6nsw7h4flbd5ccdtki232xukpi) show missing references warning for pages that are imported using xref in front matter.

e.g clicking on :cite[trustless-gateway] reference redirects to /http-gateways/path-gateway/trustless-gateway instead of /http-gateways/trustless-gateway, even though trustless-gateway is imported in front matter xref.
