LDEV-5204 Make Whiteboard always behave like it is in production mode There is a problem with image loading in Whiteboard. Uploaded images get stuck while being loaded in a copied canvas. For example after a learner enters a grouped Whiteboard activity and a canvas gets cloned for his session. It does not occur when Whiteboard is in development mode. Maybe it has to do with request proxying. We now always run Whiteboard in development mode, but make it behave like it is in production mode.
