Re: [csswg-drafts] [css-conditional] Should CSS.supports() accept !important in the 2nd argument? (#5692)

Thinking more about this, basically `CSS.supports(property, value)` is useful if it tells you whether `, value)` will work. And `setProperty` doesn't allow mixing the value and the priority, you need a third argument for that.

So `CSS.supports("background", "green !important")` should be `false` because these don't work:
```js = "green !important";"background", "green !important");
