Issue Description

Typing or pasting long values and submitting to Read-Host prompts eventually trigger a System.ArgumentOutOfRangeException

System.Exception: Prompt failed, check inner exception for details
 ---> System.ArgumentOutOfRangeException: The value must be greater than or equal to zero and less than the console's buffer size in that dimension. (Parameter 'top')
Actual value was 45.

This is related to #702

Expected Behaviour

The behavior should be consistent / no exception thrown

Actual Behaviour

I’ve observed that visually once the console output fills up the exception will be thrown on the next Read-Host try. Here’s a screencap I took. The first 2 runs of the script are fine but the 3rd throws the exception. If afterwards I run Clear-Host and try again it does not throw the exception. If I run Clear-Host before each script run (or include Clear-Host at the top of my script) I can consistently get it to behave correctly.

I also tried (instead of pasting values) seeing what would happen if I manually typed long values that wrap. It required me to do this many times until the height of the console output reached whatever height value this is – then the exception occurred.

Indeed, it’s been a while. I just tried to reproduce this and was unable to. Now if only the Azure PowerShell console didnt overwrite console output inline randomly… but I think we can close this one.

Thanks @compelx looking at your stack trace, it looks like Read-Host is calling into a legacy version of our PSReadLine experience in the integrated terminal, we hope that we can resolve this as a part of the work happening in https://github.com/PowerShell/PowerShellEditorServices/issues/1295
