The WMF uses two methods in ve.init.mw.ViewPageTarget.js to show and hide the loading indicator -- showSpinner and hideSpinner. Analogously, we currently use the showIndicator and hideIndicator methods in ve.init.mw.WikiaViewPageTarget.init.js to do the same. The hideSpinner method is properly triggered when loading of the VE is stopped, so I decided to extend that method to make use of the functionality already in place. I also wanted to extend showSpinner as well, but I found that it executed much later than our showIndicator method, causing the indicator to appear much later and not be as useful.
