Description of problem:

Noticed this in a few areas of the site but seems to occur when you have a ajax type action. For example, browse to the Sync Management page. Let the session expire for the user then click the sync now button. The app knows that user session has expired and appears to try and redirect but visually nothing happens in webui. snippet of logs:
