Re: [csswg-drafts] [mediaqueries-5] Script control of (prefers-*) queries (#6517)

Yes, because it's the *site* changing things. It's fine if the *user* communicates with arbitrary sites, as they can already do that by *visiting* the site. What we don't want to allow is sites to exfiltrate data to, say, ad exchanges, particularly when we're exploring things like [fenced frames](https://developer.chrome.com/en/docs/privacy-sandbox/fenced-frame/) to close out the few bits of cross-origin communication left.
