Funny, but it works on chrome, but not on firefox.
Strange enough there was not a single error message, it just simply didn’t work – strangest thing I have ever seen.
After some debugging, disabling the noui slider script fixed the problem. I have no idea how is that possible, since the script is namespaced to a different scope.
