 that thing, or the application using it, isn't catching SIGTSTP to return
 the terminal to a sane mode before the process suspends.
 
 Try blind typing "stty sane^J"  (ie: end with an explicit line feed,
 not carriage-return) and see what happens.

 ps: note I don't have py38-readline (or pyXX-readline for any XX) or
 python3.8 (I do have an earlier one) installed to test this hypothesis myself.
