    "path": "C:\\Program Files\\Git\\bin\\bash.exe",
    "args": ["--login", "-i"]

I think this is a dupe of a bug that has been around for a while. The devs said that they hoped it would be fixed in the latest 1.106, but I've confirmed that it's still an issue. I can't find the other defects that are related to this, hopefully they didn't get closed thinking that the defect is fixed. I'm running the latest version and I can confirm that I'm still seeing the issue when the terminal is linked to Git Bash
