Description
Portal redirects guests to the default language instead of the preferred language, when locale.prepend.friendly.url.style=2 and locale.default.request=true are set

Steps to reproduce

1. Setup EE6.2 and install portal-168
2. Add the following properties to portal-ext.properties
   locale.prepend.friendly.url.style=2
   locale.default.request=true
3. Start Liferay
4. Make sure that the default portal language is "en_US"
5. Configure browser language preferences, and set it to Japanese(ja)
6. Delete browser cookies and caches
7. Access to http://localhost:8080 as Guest user

Actual result
You get redirected to http://localhost:8080/en/ (default language)

Expected result
You get redirected to http://localhost:8080/ja/ (browser language preferences)

Note
I tested this issue with the latest Google Chrome.
This issue was fixed in LPS-35039, so it seems that this is regression bug.
It seems to be related to "I18nFilter.java".

Note2
With "locale.prepend.friendly.url.style=3" (default), issue does not happen, page is displayed in Japanese.
