Environment

Windows build number: 10.0.18362.0
Windows Terminal version (if applicable): 0.9.433.0

Steps to reproduce

1. From WSL, echo a line of text containing a literal tab character, long enough to cause the tab character to render AFTER Terminal line-wraps the line (e.g. on a second line).
2. Resize Terminal, increasing its width enough so that the whole line of text now fits on a single line
3. Print the same line of text again.

Expected behavior

The second printing of the text is printed in a single line, with the tab producing the expected amount of horizontal whitespace.

Actual behavior

The line of text is corrupted, with the tab consuming too much horizontal whitespace (= the full remaining width of the window - 1), causing the line to sill be wrapped across multiple lines as well.

I would assume this is related to the various problems listed in #4200, but I don't see this specifically mentioned (though some of the issues listed there are beyond my ability to grok).

Fully fleshed-out example:

Assuming an initial window width of approximately 80 characters, here's an example command that will print a suitable line:

echo -e "123456789 123456789 123456789 123456789 123456789 123456789 123456789 123456789 123456789 Hardtab:\t123456789 123456789 123456789 123456789"

On a smallish window, that renders something like this:

If you then resize the window wide enough that the output line is reflowed onto a single line...

... and then re-run the echo you get something clearly quite wrong:
