When running certain commands, the screen is getting cleared, and scrollback is prevented.
According the the V100 Manual, it's due to the ED Escape sequence being set to 3: https://www.vt100.net/docs/vt100-ug/chapter3.html#ED

Being able to stop the scrollback clearing would be amazing. This is a setting in iTerm "Prevent CSI 3 J from clearing scrollback history"
