Wow, that's pretty interesting... I did notice that chjj's marked was more of an "all or nothing" approach to HTML sanitization. It's good to know that your plugin can work safely alongside mine to provide an even better third option.
I was using "build & restart". I've done that many times since deactivating the chat. Now though, it's not showing that error about the chat either.
I first disabled the chat immediately after installing it over a week ago. I've done the rebuild and reload more than a dozen times since then. So that's really weird. I didn't see the icon for it after disabling it, but I was getting those errors in the browser console.
Only thing I can think is that most of the "rebuild & reload" where clicking the notification in the bottom left that said to do so rather than from the main dashboard page.
