This is now fixed on codesandbox: https://codesandbox.io/p/sandbox/happy-stallman-tlztle?file=%2Fapp%2Ftest%2F%5Bid%5D%2Fpage.tsx I've opened a PR to rename the headers to something that wouldn't be stripped: #42164

@dumbravaandrei22 please provide a full reproduction.

1. That's because of React Strict Mode: https://reactjs.org/docs/strict-mode.html 2. The Foo component is part of the layout so it doesn't rerender when you navigate a sub-layout

Thanks! This is related to the way React finds title and injects it into the head. @gnoff will have a look.

This particular error is hardcoded in TypeScript. The React team is working with the TypeScript team to resolve this. For now you can use the recommendation above 👍

Still falls under our team's work, we'll investigate 👍

I'm going to close this issue as this is behaving as intended for right now. As said in https://github.com/vercel/next.js/discussions/41745#discussioncomment-3973420 we're planning to remove it in the near future.

Looks fine!

Seems they flaked, landed 💯
