Offline directories not viewable in Files.app

Expected behaviour

When offline, the content in offline directories should be viewable in Files.app and whatever uses it

Actual behaviour

Get error “You’re offline. Check your internet connection and try again.”

The content can be viewed in the nextCloud app itself (which one should never have to use!) AND in Files.app from the Favourites side bar (if the directory is directly there—this won’t work for subdirectories of offline directories). Files at the toplevel of the offline directory can also be opened when gaining access through the sidebar.

Steps to reproduce

Go offline and try to open.

I’m getting ready to give up and pay for an iCloud subscription. It’s not expensive but I have principles… Unfortunately the nextCloud iOS app, while it has never been exactly good, has become more unreliable than iCloud which is saying mountains considering that Steve Jobs must be rolling in his grave at light speed given the way-worse-than-Windows95 quality of Apple software these days. Even though iCloud does not support offline files, it’s more likely to actually have the file downloaded than the nextCloud app is to give me access to the file (that is downloaded—I make periodically sure of that as auto-refresh has never worked).

The issue names Files.app, offline directories, and the Nextcloud iOS app but no source files or tests. Begin by reproducing the failure while offline and trace how offline directory access is handled for Files.app, including nested directories. Done means offline directory contents and their files open through Files.app without the offline error.
