I asked people around to test using Debian, and we do have a
confirmation that Debian + Emacs 27 and Debian + Emacs 28 do trigger the
error.

I also installed Debian 11.6.0 on virtual machine, and I was also able to
trigger the error, following the provided steps, using the Emacs 27
installed via apt-get.

The problem seems to be real and appears to be some combination of
Debian/Ubuntu + Emacs.

Considering the popularity of Debian-based distros, may someone take a
closer look on what may be going on? Since the latest Emacs release also
suffers from the problem, I am afraid that the issue will be present in
the coming Emacs 29 as well (I recall no related fixes in recent Emacs).
