Meta tags are moving to <body> tag instead of <head> tag #82485
Description
Link to the code that reproduces this issue
https://github.com/dmythro/next-meta-bug
To Reproduce
bun ibun run build && bun start- Refresh the page until you will see meta tags in
<body>
Current vs. Expected behavior
Sometimes I get meta tags inside <body> on production builds, which breaks the SEO etc. Just keep refreshing the page until you see it.
On my main project it happens almost always, I'll see if I can improve this example for reproduction later (I've been adding patterns from my project until started seeing meta tags in <body> instead of the <head>).
