I now believe this is a bug in Git because calling `git status` fixes the problem.

1) Create a hard link to a file in a Git repo.
2) Call `git status`.
3) Call `git reset --hard`.

Without 2), Git severs the hard link. With 2), the hard link is preserved.

This occurs for me on Debian 10 & 11, as well as Git 2.30.2 and 2.20.1.
