Cached version of page has wrong language context

Following up on https://discord.com/channels/501836936584101899/506916956637495306/806574179578544148

Steps to reproduce:

• create a fresh grav project composer create-project getgrav/grav
• change to flex pages by adding type: flex to the pages settings in the system.yaml
• add a new file pages/01.home/default.de.md and add some content
• add the following language settings to system.yaml

  default_locale: de
  languages:
    supported:
       - en
       - de
    default_lang: en
    content_fallback:
      de:
        - en

• load the de homepage by adding /de/
• everything looks fine on the first hit (page shows content of pages/01.home/default.de.md)
• reload page
• page shows content of en version (pages/01.home/default.md) despite of being in de context

I think this might be an issue with the caching or with flex itself - either way, this was working in previous versions (certainly before the 1.7 stable release). If you need info on the exact version where this was working I can dig a bit in our codebase to get it.
Please let me know if I can help any further or you need more information.
And thank you guys for taking care, this is really appreciated!
