Hi team,

Our customer found an issue that the GUEST_LANGUAGE_ID cookie was overridden when accessing from the site virtual host.

Steps to reproduce:

1. Create a new site called (Site A)
2. Enable only English language (en-US)
3. Add a virtual host under Public Pages in Site A with the default language. (Ex: site-a.local)
4. Create a new public page in Site A called (Home) and publish
5. Create a new site called (Site B)
6. Enable only French (fr-FR)
7. Create a new public page in Site B called (Home) and publish
8. Access Site B using the virtual host from Site A. (Ex: http://site-a.local.local/web/site-b)
9. On Browser open the development tool and inspect GUEST_LANGUAGE_ID

Expected result: The GUEST_LANGUAGE_ID should be fr-FR

Actual result: The GUEST_LANGUAGE_ID was changed to en-US (Site A language)

Note: It works correctly if accessing from the virtual instance host e.g. http://localhost/web/site-b
