I doubt it is being built differently than screen normally is.

Nah, it's a rather ad-hoc definition grown from what should be an Eolie
container from the cookbook (also refer to #47097).
guix environment --preserve='^DISPLAY$' --preserve=XAUTHORITY \
--preserve=TERM \
--expose=$XAUTHORITY \
--expose=/etc/machine-id \
--expose=/etc/ssl/certs/ \
--expose=/sys/block --expose=/sys/class --expose=/sys/bus \
--expose=/sys/dev --expose=/sys/devices \
--ad-hoc epiphany nss-certs dbus procps coreutils psmisc screen
Given that I expose most of /sys explicitly, you should take the above
with a grain of salt.

I'm not personally impacted by this bug or anything, it's much rather a
follow-up to my attempted fix of #47097. I think there might be some
flaw in trying to run a sandbox inside a sandbox (like bubblewrap
inside `guix container`), that doesn't actually improve security in any
meaningful way.
