Terminal text remains italicized after running a command which outputs italic word.

### Describe the bug

I encountered a visual bug, that the terminal text style persists in italics after running a command which outputs italics word. I tested `ls` and `pwd`. `ls` caused this bug but `pwd` did not.

You can ask copilot to answer you about \e[0m, to fix this visual bug. It's funny.

I thought it's a bug, but I'm not sure if it was `starship`, `windows terminal`, `pwsh` or something else caused it. If you want more info of my environment, I'd love to provide it.

### Affected version

GitHub Copilot CLI 0.0.407.

### Steps to reproduce the behavior

1. Open PowerShell.
2. Ensure `ls` (or another command) produces output with italic formatting.
3. Launch copilot.
4. Run `ls` (change to command mode and input `ls`).
5. Observe that after the command output is displayed, the Copilot CLI input prompt and subsequent text remain italicized.

### Expected behavior

The input and output formats of copilot itself will not be affected by unexpected factors.
