I see problems as well, I will disable the control for now until I have time to work on it.
The CDN (Content Distribution Network) this control is using seems to be unavailable:
https://twemoji.maxcdn.com/v/13.0.0/svg/1f600.svg
Let me see if I can update it to a new one. Thanks for letting me know.
Edit: I've disabled Twemoji on the control for now. It works but it's a mismatch in the emoji styles now. Will fix it later.
