Environment

Win32NT 10.0.18363.0 Microsoft Windows NT 10.0.18363.0

Any other software?

Windows Terminal
Version: 1.0.1401.0

Steps to reproduce

Compile and run MS Docs example "Example of Select Anniversary Update Features" on https://docs.microsoft.com/en-us/windows/console/console-virtual-terminal-sequences#example-of-select-anniversary-update-features

Expected behavior

Draws using VT100 ANSI Escape sequences.

Actual behavior

Looks like VT100 sequence to move cursor using tabs works only on current line and does not move to next line when there are no more tab stops on line.

This works fine on Powershell and CMD when not inside Terminal and fails with Powershell and CMD when inside Terminal.
