I think there’s an issue here, but I’m not exactly sure what…

Clean project, enable `LocaleMiddleware`:

```auto
from django.conf.urls.i18n import i18n_patterns
from django.urls import path
from django.http import HttpResponse

def hello(request):
    return HttpResponse("hello")

urlpatterns = i18n_patterns(
    path("", hello),
    prefix_default_language=True,
)

```

`/en/` 200.  
`/en-gb/` 200  
`/en-us/` 404

```auto
Using the URLconf defined in ticket_31540.urls, Django tried these URL patterns, in this order:
    en/
The current path, en-us/, didn't match any of these.

```

So this is because [`en-us` isn’t a configured language](https://github.com/django/django/blob/master/django/conf/global_settings.py#L51) but when determining the language we fellback to `en` correctly I guess, but then we didn’t resolve the URL using the same, or redirect to the fallback language URL.

It seems like that’s something we should do, or… ?
