[csswg-drafts] [css-typed-om] Is using a constructed expression of the form 1px/1px invalid as a <number> (#10733)

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

== [css-typed-om] Is using a constructed expression of the form 1px/1px invalid as a <number>  ==
The WPT test [css/css-typed-om/stylevalue-subclasses/cssScale.tentative.html](https://wpt.fyi/results/css/css-typed-om/stylevalue-subclasses/cssScale.tentative.html) requires that the following throw an exception:

```js
let coord = new CSSMathProduct(CSS.px(1), new CSSMathInvert(CSS.px(1)));
let scale = new CSSScale(coord, 0);
```

with a description calling the product "an invalid division by px/px".

I can't find where (or if) this is required by the current CSS Typed OM draft (and it may just be an invalid test, it is marked tentative), but may be missing it.

Should this be invalid?
