[csswg-drafts] [css-mediaqueries-4] Unused mf-eq token in level 4 (#5457)

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

== [css-mediaqueries-4] Unused mf-eq token in level 4 ==
In the [syntax](https://www.w3.org/TR/mediaqueries-4/#mq-syntax) section, `<mf-comparison>` includes a rule for `<mf-eq>`. I think that would imply that syntaxes like:
```css
@media (min-width = 600px);
```
are valid. 

However, I didn't see any other informal mentions of `=`'s syntax in the spec, or why it'd be interpreted differently from the existing`:` syntax (e.g. `@media (min-wdith: 600px);`).

I see that this change was made in https://github.com/w3c/csswg-drafts/commit/d8e702d0a696a6d58592972ed4c1c473e02a7c17 without (I think) intending to introduce this syntax, as `<=` and `>=` are covered by `<mf-lt>` and `<md-gt>` productions.

Is this an error in the spec, or is there something I'm missing?
