Environment

Windows build number: Win32NT 10.0.18362.0
Windows Terminal version (if applicable): 0.5.2762.0

Steps to reproduce

echo -e '\e[4m underlined \e[33m yellow \e[39m should still be underlined \e[m'

Expected behavior

The entire line should be underlined.

Actual behavior

The "should still be underlined" bits aren't underlined.

Note that SGR codes 22, 27, 39 and 49 seem to cause this effect, but only if they're predeced by a 1, 7, 30-37 or 40-47, resp., that is, only if they do actually turn off some other attribute.

Also note that if the "should still be underlined" text is made longer so that it overflows to the next line (or even multiple new lines), it's underlined in the last one of these lines. This makes it perhaps a reincarnation of #47.

Furthermore, changing the window width and thus causing a reflow of the text removes the underlining from the last line.
