Comment:

 I've been thinking about this overnight, my proposal:

 * punt it from PHP, we don't know if the client requires the PNG or SVG
 CDN at that point. They can differ, although don't by default
 * if the client fails the browser sniff, add a preconnect to the
 appropriate CDN via JS per the spec. The preconnection will happen while
 twemoji runs.
 * per my comment in ##34292, I'm not concerned about the extra connection
 client side but less keen for the sake of the CDN.

 Thoughts?
