Installing in a different language than en results in a broken homepage link

I could not reproduce (anymore)

- drush si -y --locale=fr
- drush en -y la_eu_default_content
- drush pmu -y default_content
- Default configuration for the homepage (/admin/config/system/site-information) is /homepage
- As long as this path exists, works as expected when accessing from /
- Tried with and without language prefix set in /admin/config/regional/language/detection/url

I also can't reproduce this, but... While I was trying to set up and re-set up, at some point switching between importing existing configuration from the repository (ddev drush si --existing-config) and fresh install with a different language (drush si -y --locale=nb), I saw the /en/homepage being used as a homepage url. Refreshing the page, logging in as admin or clearing caches was solving the issue, so it might be some caching issue - maybe not related to the project itself.
