nmtui: keypresses randomly eaten
Since about Ubuntu 18.04 (reproducible also with both disco and eaon) nmtui randomly skips keypresses when exiting certain menus.
One such situation is when re-configuring a network in the edit network menu, entering the network configuration submenu, doing some keypresses and hitting ESC to return to parent menues. In certain situations nmtui seems do eat keys and misinterprets arrow keys as command to exit. Sometimes after exiting the next character entered in the console (in my case LXTerminal on Lubuntu/LXDE) gets also eaten.
