Environment

Win32NT 10.0.18362.0 Microsoft Windows NT 10.0.18362.0

Windows Terminal Version: 0.3.2171.0

Other Software

ruby 2.6.3p62 (2019-04-16 revision 67580) [x64-mingw32]
gems
pry (0.12.2)
irb (1.0.0)
both ruby REPLs

Steps to reproduce

In windows terminal start the ruby REPL pry or irb

type fooar then press the left arrow key to move the cursor back.

Expected behavior

You should be able to use the arrow keys to move around.

Actual behavior

The cursor is stuck at the end of the line.

I tested this behavior in other REPLs such as node, and python and this was not an issue. I then tested this behavior in other shells cmd and powershell (not in windows terminal) and this behavior was not reproducible.

Did some further testing and noticed this issue is a problem both in powershell and command when I start them in windows terminal, but it is not an issue when I run wsl in windows terminal.
