[Bug]: SMB share on Windows with any folder junctions in the share prevents share folder listing in web browser and Nextcloud Android client

⚠️ This issue respects the following points: ⚠️

• This is a bug, not a question or a configuration/webserver/proxy issue.
• This issue is not already reported on Github OR Nextcloud Community Forum (I've searched it).
• Nextcloud Server is up to date. See Maintenance and Release Schedule for supported versions.
• I agree to follow Nextcloud's Code of Conduct.

Bug description

If I have a junction (linked folder) inside the share, the share shows no files/folders at all.

Steps to reproduce

1. If I remove the junction folder inside the share, then the share shows all files and folders.
2. If I create a junction folder inside the share, then the share shows no files and folders.

Expected behavior

Should show all files and folders and not fail because of any particular issue?

If support of junction folders isn't available, then ideally ignore that file/folder but at least still list the rest of the files and folders in the share.

The issue names no source files, tests, or entry points. Reproduce the Windows SMB share behavior with and without a folder junction, then trace the server-side share listing failure; done means regular files and folders remain visible when a junction is present, or the junction is safely ignored.
