hey,
i was curious, so i tried it on the only machine i have sudo installed on,
which is my Debian based Ubuntu based LinuxMint Laptop.
micha@HP-Laptop: ~
> errors=$(sudo apt-get install mirage 2>&1 1>/dev/tty)

then i switched to a shell, opened i with 'sudo tmux'

Abort.
so i looked into /etc/sudoers and all /etc/sudoers.d/* and found two
suspicous flags:
/etc/sudoers:
Defaults use_pty
/etc/sudoers.d/0pwfeedback:
Defaults pwfeedback
then consulting the sudo manpage convinced me, it was the 'use_pty' flag
(in section SUDOERS OPTIONS). after removing that flag everything works as
'expected':
