I have a setup where all assets downloaded are only within the applications domain. So while the gantt chart is displaying without issues locally, in a deployed environment where content security policies are in place, the css resource [https://webix.io/dev/fonts/wxi/wx-icons.css] returns with a "(blocked:csp)"
The easiest alternative is to directly download the css file and throw it in the application code. But is that allowed under SVAR licensing terms? (our company is planning to buy either an Application or Team license)
