Emoticons are still being replaced when copy'n'pasting text, that contains one out of the list.

Thank you!

thank you god

a small downside of this is that the searching for emojis e.g. :smile breaks when the search term starts with an "emoji"
e.g. I can't search for :pray because the script kills the :p

I have never written tampermonkey scripts myself and have no clue how to address this, but maybe someone here has an idea 👀

You, sir, are a legend 🫡 Thank you for fixing this script!

I've created an alternative script that takes a different approach and instead of manipulating the DOM it patches the webpack chunks/functions that do the conversion so instead of undoing the converted emojis it prevents the app from changing them in the first place. Should also fix @jemand771's issue as well as copy-pasting. Will not work by copy-pasting it into the console as it has to be executed before any other javascript loads.

Ah, that looks great thanks! This is indeed a very ad-hoc fix, since I did not find out where the conversion exactly happened, and your approach just removes it completely. Great job, thanks!

Perfect! Thanks :D
