Archinstall hangs on "custom-commands" when it needs a user input

[ghost]

I have set the custom-commands part in the config file as this:

"custom-commands": [
        "pacman-key --recv-key 3056513887B78AEB --keyserver keyserver.ubuntu.com",
        "pacman-key --lsign-key 3056513887B78AEB",
        "pacman -U 'https://cdn-mirror.chaotic.cx/chaotic-aur/chaotic-keyring.pkg.tar.zst'",
        "pacman -U 'https://cdn-mirror.chaotic.cx/chaotic-aur/chaotic-mirrorlist.pkg.tar.zst'"
        ...
]

Archinstall hangs on the third command (pacman -U) without showing any output. Obviously, it was waiting under the hood for a confirmation (Y/n) to proceed to install but that text was not shown. And even when pressing Y then Enter, it does nothing.

In this case, adding --noconfirm to pacman -U can make it install without waiting for user input. But in other cases,
Archinstall should shows the output of the customs commands and accepts the input if needed.
