in global.service.ts, in the constructor for Globals, use this to patch webPlatform in case setGlobalRefreshHandler is not defined (replace the current code)

          if (!this.webPlatform.setGlobalRefreshHandler) {

          this.webPlatform.setGlobalRefreshHandler = function (handler) {

              window.parent["WEB_PLATFORM"]["refresh" + window.name] = handler;

          };

     }
