Comment (by dd32):

 > 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.

 This seems like the more correct option over always performing it,
 although it's only shaving a few ms in the event that a emoji is in use.
 I'm not sure myself if it should be in the list at all, a fallback emoji
 loading a few ms later isn't going to be the end of the world, and
 browsers are getting better at supporting everything already.
 I'd say the vast majority of WordPress sites don't actually have any
 Emoji's on them, so a few ms in those cases would be fine.
