Update status detail after leaving overlay

This is currently used for poll voting; after voting in a
poll overlay, the status detail will update with the user's
vote and the new vote count when they dismiss the overlay.

As part of this change, the refresh_status_detail method now
maintains the scroll position after refresh, rather than
scrolling back to the top automatically
