Public link exposes full name from profile

[AND51]

Steps to reproduce

1. Fill out your profil under Settings→Personal Info
2. Create a folder
3. Create shared link
4. Open shared link in a new window

Expected behaviour

Sometimes I use a (write protected) shared link to share a folder with files. I post this shared link on various untrusted websites or places.

When I recently tested such a link in icognito mode, I noticed that my full name is written in the upper left corner: "FOLDER_NAME geteilt von MY_NAME"

I've set visibility of "full name" to "contacts". The description says, "Visible to local users and to trusted servers." However, an anonymous user is not a "local user". My name is even displayed when choosing "local", which states, "Only visible to local users."

I expected that no name is written, just the folder name.

Actual behaviour

My name is displayed in the upper left corner, no matter which privacy setting is chosen.

GitMate.io thinks possibly related issues are #2334 (Move files expose complete folder structure on public links), #6418 (Some content leaks to public from the user profile ), #1639 (Unable to access public shared link), #318 (Public links for calendar), and #6719 (Changing LDAP user Full Name).

@nextcloud-bot From your suggestions, only #6418 (Some content leaks to public from the user profile ) seems to match my issue roughly.
