JoinMarket user input prompts sometimes don't show up

[dmp1ce]

When running a coin join or tumbling, the user prompts often do not show up. The user can still input the data but it isn't clear what is supposed to be entered.

This always happens during a sendpayment when the user is normally asked to confirm with a y. The script will pause waiting for the input, even though the prompt which would normally show up is missing.

A work around is the use --yes to answer yes to all questions. Be careful using --yes because you might accidentally agree to fees which you didn't want!

The reason for this issue likely has to do with how Docker or Docker Compose is treating TTY, but I haven't been able to find a fix.
