Tickets with new Messages are not Bold anymore

Tickets with new Messages are not Bold anymore

Hello

We just made the update from 11200 to 11300. When someone sends a reply to a ticket, it used to change the Font of the Ticket in the Request list view to bold. In 11300 this does not happen anymore. This makes it hard to notice if there are any new answers to a ticket. You basically just have the notification bell, which most of us do not use. Is this a bug? Is there an option to change this?
