 The default URL is currently `set_url_scheme(
 '//s.w.org/images/core/emoji/72x72/' )` but the CDN is SSL-only, so in
 case `set_url_scheme()` returns "http" the request gets redirected to
 "https". That's pretty bad for our little friends.

 It's seems like this was an oversight in [31938] because s0.wp.com has no
 such redirect.
