There is also no way to detect support for the even more relaxed syntax where selectors can start with an identifier.

In Chrome 113 :

```js
CSS.supports('selector(& bar)')
// true
CSS.supports('selector(bar &)')
// true
```

Safari TP doesn't seem to work at all :

```js
CSS.supports('selector(&)')
// false
CSS.supports('selector(& bar)')
// false
CSS.supports('selector(bar &)')
// false
```

This seems problematic if the plan is to relax the syntax somewhere in the future.
