[🐞] useDocumentHead returns a non-serializable value which cannot be tracked directly

[ianlet]

Which component is affected?

Qwik City (routing)

Describe the bug

When using the useDocumentHead hook to access head data (e.g. values added in the frontmatter in MDX files), we cannot directly track the head value for changes:

export default component$(() => {
  const head = useDocumentHead();

  const authorId = useComputed$(() => {
    return head.meta.find((m) => m.name === "author")?.content; // <--- ESLint not happy
  });

  // ...
});

  51:12  error  When referencing "head" inside a different scope (useComputed$), Qwik needs to serialize the value, however "head.styles.props.ref" is a function, which is not serializable.

It is however possible to bypass this by simply destructuring useDocumentHead() return value directly:

export default component$(() => {
  const { meta, frontmatter } = useDocumentHead();

  const authorId = useComputed$(() => {
    return meta.find((m) => m.name === "author")?.content; // <--- ESLint happy
  });

  // ...
});
