Bug description

When sharing a folder via editable public link, anonymous viewers cannot move files, because the file move dialog doesn't load.

Steps to reproduce

1. Share a folder with public link and enable editing
2. As an anonymous user access public link and select "Move or Copy" menu item of a file
3. File move dialog doesn't load files due to HTTP 401 status codes on webdav

Expected behavior

The file move dialog should load and allow selecting a folder to move/copy the files into.
