Case activities list no longer reloads after inline activity status change

I was testing the inline 'Change Activity Status' feature in 4.4 and 4.5 in order to fix a minor bug in URL formatting reported by Lola (https://issues.civicrm.org/jira/browse/CRM-14467) - and I noticed this regression.

Go to Manage Case and click on the 'status' column for one of the activity rows in the Activities selector. You get a pop-up to change the status. In 4.4, after changing the status and clicking ok, the selector listing reloads displaying the updated status for the modified row (and changing the order generally as well since status is part of the ORDER BY). In 4.5, the selector listing does not reload. You have to reload the entire Manage Case page to see the updated activity status.
