Issue

A Hydration completed but contains mismatches error occurs when the root page is redirected to another language page based on browser language detection in a statically generated site.

Reproduction Steps

1. Use locale messages in the template.
2. Make it so that the detectBrowserLanguage cookie stores a non-default locale.
3. Directly access the root page, which triggers a redirect based on the locale saved in the cookie, resulting in a hydration error.
