Environment

Windows build number: Win32NT             10.0.18363.0 Microsoft Windows NT 10.0.18363.0
Windows Terminal version (if applicable): 0.9.433.0
Git: 2.25.0 (also reproduced with 2.17.1)
Vim: 8.0 (also reproduced with Vim 8.2)

Steps to reproduce

• Run a WSL2 instance (Ubuntu)
• Clone any Git repository
• Begin a rebase git rebase -i HEAD~2

Expected behavior

The cursor should be at the beginning of the line:

Actual behavior

The cursor position is not at the beginning of the line:

Other notes:

• When running WSL (bash.exe) through the command prompt (Linux host), it works OK. But then I'm not using Windows Terminal.
• When running Git directly on Windows with the command prompt, it also works OK. But again, it's not using Windows Terminal.

So I think this is a Windows Terminal bug.
