Requests show in bold still broken after 7012

Although the 'asset disappearing when changing the category of a request' has been fixed the 'request showing as bold again after category change' bug is still present!

If I put in a new request it shows in bold, which is fine. Then I 'Pickup' the request and it no longer shows as bold, which again is expected behaviour. However, when I change the category of the request through the 'View Request - Request Details' screen and click the little green tick the Request shows as bold again. This is a bug as the request has been picked up and therefore should not show as bold unless it becomes 'Unassigned' again.

Please confirm that you are able to re-produce this behaviour as we have repeatedly.

Thank you.
