This doesn't repro on 2.0.0-beta.4 on Ubuntu 18.04

@SteveL-MSFT - This has been reported multiple times and likely is still an issue as nothing has been done to avoid the exception. But you might tag it as a dupe when you find the similar issues.

close as a duplicate of #991

Keep this issue open, as #991 is originally about a ArgumentOutOfRangeException.

I took a closer look at this issue today and I think the issue had already been fixed by #790, which changed the implementation of ClearScreen from using Console.ScrollBuffer, console.SetCursorPosition and console.SetWindowPosition to applying the escape sequence "0x1b[2J".

That change was included in 2.0.0-beta4 and newer versions, this issue was reported to happen in 2.0.0-beta3.

@sorge13248 Please try out the 2.0.0-rc1 version of PSReadLine from PowerShell Gallery.
