Hi again :) I noticed another incorrect warning from the bug meter, triggered by https://hackinpovo.it, this time saying: This <link> element must be inside the HEAD section. Which is not true. Citing the HTML spec. From both <https://html.spec.whatwg.org/review-drafts/2020-01/#allowed-in-the-body> and <https://html.spec.whatwg.org/dev/semantics.html#allowed-in-the-body>,

If a link element has an itemprop attribute, or has a rel attribute that contains only keywords that are body-ok, then the element is said to be allowed in the body.

From both <https://html.spec.whatwg.org/review-drafts/2020-01/#body-ok> and <https://html.spec.whatwg.org/dev/links.html#body-ok>,

The body-ok keywords are dns-prefetch, modulepreload, pingback, preconnect, prefetch, preload, and stylesheet.

Not ideal, I agree, but that's what it says :/
