when starting git gui in Powershell 5.1, next line shows ANSI codes

[peetrike]

Environment

Windows build number: 10.0.18363.0
Windows Terminal version (if applicable): 0.7.3291 (and 0.6.2951.0)

Any other software?
Git for windows (v2.24.0.windows.2)
Windows Powershell v5.1

Steps to reproduce

1. On Windows Powershell prompt enter git gui
2. On next line start entering next command

Expected behavior

the entered text shows as it is supposed, with correct coloring from PSReadline.

Actual behavior

ANSI escape codes are showed until Enter is pressed. The actual input is correctly executed.

When PSReadline module is removed from session, the problem ceases to exist.

This is a bad interaction between PSReadline and git -- one or the other is failing to restore the console mode to one that supports VT. Does it work with the new PSReadline verison in PowerShell 6/7?

(closing this as it's a shell/application issue)
