steps:

1. open WSL terminal in VSCODE
2. type anything and the input is fine.
3. press the "UPKEY" for the first time and the input shows like if I pressed insert.
4. I'm saying shows because when I press KEYUP after entering the input the input is correct.
5. You can watch to GIF to understand it.

Pressing the "insert" key doesn't have any effect.

Powershell works fine.

WSL terminal works fine outside VSCODE

EditorConfig was messing with my terminal for some reason, disabling it fixes the problem
