SignalR jQuery plugin fails to load when the Angular Report Viewer is present in the same application. Removing the following lines from each instance in Reporting package resolves the issue but may introduce other issues:
window.$ = jquery;
window.jQuery = jquery;
For example, removing the above lines results in the error '$.throttle is not a function' in the 'continuous scroll' mode of the viewer. The workaround is to use the 'single page' mode.
