killing nslookup with Ctrl C breaks the terminal display

Summary

running nslookup and then hitting ctrl+c causes the terminal to not display (but still receive and process) user input until reset is ran

bind-tools version used

9.13.5-2, also running antergos on linux kernel 4.20.3

Steps to reproduce

1. open any terminal running any shell
2. run nslookup and hit enter 3.(optionally but increases my reproduction rate from ~90% to 100%) type server and hit enter
3. hit ctrl + c
4. start typing and see if text is displayed

What is the current bug behavior?

terminal stops displaying text after exit

What is the expected correct behavior?

terminal should continue to display text after exit, which my terminal does with similar commands

Relevant configuration files

I haven't modified any

Relevant logs and/or screenshots

screenshot shows bugs reproduced on multiple terminals (xterm, uterm, etc) with multiple shells on an up to date version of antergos immediately following a reboot. on each terminal I ran nslookup + server and hit ctrl c, ran 2 commands without my text displaying to the terminal, then dropped into an sh shell from the bash shell and did the same thing
