Environment

Windows build number: [Version 10.0.18362.145]

Windows Terminal version (if applicable): n/a

Any other software? wsl, nano

Steps to reproduce

1. In either powershell or cmd in terminal, type wsl nano
2. Execute taskkill -im wsl.exe -f to kill wsl
3. Type cls in the terminal where wsl was open

Expected behavior

cls should clear the screen and make the terminal behave like it used to before wsl nano

Actual behavior

after killing wsl powershell/cmd is in a bugged state because nano takes up the whole screen
cmd: cls won't clear the screen (first screenshot)
powershell: cls will clear screen BUT if the user inputs e.g. "cls", terminal will print "cclcls", yet still interpret it as "cls" (second screenshot)

This issue is also present in the original cmd/powershell.
