varkor / WhatsApp Emoticon Preserver

Hallo,

I installed the Whatsapp Emoticon Preserver directly and installed it onto Tampermonkey for Google Chrome.

Problem is, I've never seen it work once. There seems to be some sort of error in the script saying "Function declared in a loop contains unsafe references" but I doubt that affects it if it's left in?

Could you help me troubleshoot or fix this please? Or just tell me to reinstall or something.

Sorry for the long message
