Is this a bug or I am doing something wrong?
```
\documentclass{article}
\usepackage{fontspec}
\begin{document}
\fontspec[Color = {red}]{NewCMMono10-Book.otf}%
abcd
\fontspec[%
Color = {green},%
Width = {20}%
]{NewCMMono10-Book.otf}%
abcd
\end{document}
```

I was expecting the width of the characters to have changed as explained in the documentation.

`FakeStretch` is the required key (Courtesy: https://tex.stackexchange.com/a/429637/).
```
\documentclass{article}
\usepackage{fontspec}
\begin{document}
\fontspec[Color = {red}]{NewCMMono10-Book.otf}%
abcd
\fontspec[%
Color = {green},%
FakeStretch = {0.75}%
]{NewCMMono10-Book.otf}%
abcd
\end{document}
```
