Originally created by @daanx on GitHub (Aug 4, 2021).

Windows Terminal version (or Windows build number)

10.0.19042.1110 (windows terminal 1.9.1942.0)

Other Software

No response

Steps to reproduce

When the windows is horizontally resized the cursor position is lost; on the narrowing the cursor wraps to the next line, but on widening again the cursor goes incorrectly to the start of the previous line.
(Extra heisenbug: if you quickly resize narrow again the cursor will go randomly in the text :-)

To reproduce run the following batch file:

@echo off
set /p "ANSWER=prompt prompt prompt prompt prompt prompt prompt>"

Expected Behavior

On the old cmd terminal the batch file works as intended.

Actual Behavior

Here is what happens in Windows terminal (I colored the cursor in red):

perhaps this is related to the earlier bug I filed #10848 ?

This probably is closely related, maybe even the same root cause, but I like having lots of test cases, and these are great repro steps. Thanks!

I'm trying to reproduce this bug to test if #15701 fixed it but couldn't do manage to reproduce it. Does this bug still happen in 1.17/1.18?

BTW I think we should close this issue in favor of #10848. From what I can tell they're the same issue if anything. Also, I managed to reproduce something although not using the given instructions. I'll comment in #10848.
