@Nicolas Hmmm... well, that's unfortunate, it looked good. I can tell you that the javascript is completely missing on the client side code.
The actual plugin seems to be transforming the content in the simple case, just doesn't seem to be transporting the active JS to the client.
After de-minifying then nodebb.min.js and searching through to find if any of your tags are referenced, they are not. Issue seems to be with the public/js
folder not being included with minified javascript?
Don't know if that helps, but I may muck around a bit to see if I can get it working.
