When pressing Ctrl+S, copilot does not run a command

### Describe the bug

When I press Crtl+S after entering a command (`ls` for instance), instead of running the command Copilot CLI just display `/` with autocomplete for slash commands.

### Affected version

### Steps to reproduce the behavior

1. Open GitHub Copilot CLI using copilot
2. Type `ls` and then press `Ctrl+S`
3. The text disappear and you can see the `/` symbol with autocompletion for slash commands
