[csswg-drafts] [css-font-loading] When using FontFace on a worker, what viewport should viewport relative units use? (#13909)

weinig has just created a new issue for https://github.com/w3c/csswg-drafts:

== [css-font-loading] When using FontFace on a worker, what viewport should viewport relative units use? ==
When using the [FontFace interface](https://drafts.csswg.org/css-font-loading/#fontface) on a worker, what viewport should viewport relative units use?

For example, how should something like this be interpreted when on a worker?

```js
const font = new FontFace("my-font", "url(my-font.woff2)");
font.stretch = "calc(10% + (sign(1vw - 100px) * 5%))";
```
