Describe the Bug

When a create files

head.js :

export default async function Head({ params }) {
  return (
    <>
      <title>Title head</title>
      <meta name="description" content="Generated by head" />
    </>
  );
}

layout.js :

export default async function RootLayout({ children }) {
  return (
    <html lang="en">
      <head>
        <title>Title layout</title>
        <meta name="description" content="Generated by layout" />
        <meta name="viewport" content="width=device-width, initial-scale=1" />
        <link rel="icon" href="/favicon.ico" />
      </head>
      <body>{children}</body>
    </html>
  );
}

Tags < title > and < meta > are not deleted, just add another tags in html structure :

I tried with async function and normal functions,

Thank’s

Updated today to NextJS 13.0.3, but the issue is still present, all my schema.org meta tags are moved from the body to the page head creating a mess of multiple titles and descriptions on the posts list page.

komzweb, I’m doing more/less the same now, but previously I simply accessed the post title in layout via children.props.title It was a much more convenient way instead of creating a separate head file for each post. I’m not using API for posts (they are simply stored in js files, because of better SEO optimization possibilities, which are not available when JSON/markdown is in use). Would be nice if someone from dev tell here how to access children’s post title from the layout, if possible. As from the docs passing props and vice versa is not possible.
