Well yes, since that test file is part of my Emacs configuration it has
some syntax highlighting (everything is by default since it's run with
‘-Q’ flag).

Modes? You can check yourself, I just started Emacs without config, then
opened one of my init files and pressed ‘C-x C-=’, then scrolled. That's
all.

Yes I can reproduce it in Fundamental mode too.
