Comment (by peterwilsoncc):

 Replying to [ticket:33210 pento]:
 Was the ~90ms saved hard coding in HTML or adding via JavaScript once the
 result of `( ! settings.supports.simple || ! settings.supports.flag )` is
 known?

 If it's added, adding it via JS while twemoji is running would avoid any
 ill-effects in browsers supporting emoji.
