Kate editor directory view shows only git untracked files

I have a directory fetznerdotme in a sub directory of my user’s home directory.
I am logged in as my ordinary user, who also owns the home directory and all subdirectories.

I open the directory in Kate text editor with File > Open Folder > (… select the directory in the menu… ) > OK

In the left sidebar of Kate, where it shows the folder contents, I see only those files and folders NOT tracked by git:

archetypes/
public/
resources/
themes/
.gitmodules
.hugo_build.lock
hugo.toml

The output of git status is

...
Untracked files:
  (use "git add <file>..." to include in what will be committed)
        .hugo_build.lock
        archetypes/
        hugo.toml
        public/
        resources/

The full contents of the directory are

drwxr-xr-x@   - alex  5 Dec 01:43 themes

The directory is a git repo, and it does contain a git submodule.
My local git version is git version 2.52.0
There is no .gitignore, .git/info/excludeis empty except for some comments

❯ cat .git/info/exclude 
# git ls-files --others --exclude-from=.git/info/exclude
# Lines that start with '#' are comments.
# For a project mostly in C, the following would be a good set of
# exclude patterns (uncomment them if you want to use them):
# *.[oa]
# *~

Other, non-git directories appear complete

I cannot identify a setting in the menu that would toggle git visibilty.
I would expect a behavior of hiding git ignored files, but not git tracked files

Can anyone help me identify what’s causing this behavior?
