 I think the Wordpress emoji code is not loaded responsibly.

 I did some experimentation.

 When I disable emojis and move all external js to footer and even load
 external styles asynchronously with some above the fold css inlined -
 except Google Fonts - I observe is that fonts are fetched immediately
 after Google fonts css is downloaded.

 On the other hand, if I don't disable emojis, both the initial fetch of
 Google Fonts css and the subsequent fetch of fonts are delayed. Both.

 My conclusion is that the javascript delays both link fetches and CSSOM
 building.

 This I tested on Browserstack on OSX on Chrome and Safari.

 Sorry, don't have a demo as this is complicated.
