I did this all at 1-2AM, and published at 6am, so forgive me on the few hiccups.
- I can reproduce the button disappearing, darn thing is stubborn. I managed to fix it, I think.
- I suppose I forgot something about the Font Awesome Icons. You need to go to your sites settings, and go to the SVG Subset, and manually add it. If Discourse doesn’t already have it in use, it won’t render by default. Though, even doing this I still had an issue with it not rendering. I will look into this further.
This has been pushed out.
