Javascript error on 28

Yep, needs an update for F2V compatibility

Does this break access to files and dirs marked as favourites prior to the upgrade to 28 for anyone else?

This also breaks access to selected files

I see this error in 28.0.3 of Nextcloud after a recent update. It breaks UI things for file copy and move it seems.
Other errors encountered are this one nextcloud/server#43953 which seems to be merged but not in 28.0.3 - perhaps that is related ?
I also see Error: Invalid owner type when using right click - Move or Copy which points to a variety of closed bugs.

Also : https://docs.nextcloud.com/server/latest/developer_manual/app_publishing_maintenance/app_upgrade_guide/upgrade_to_28.html#removed-apis mentions :
OCA.Files: Everything removed but Sidebar and Settings. See the Added API section for replacements.

There is no mention on how to replace the specific OCA.Files.FileList in that document as far as I can see.
