When getting new articles for all groups, the number of unread messages in each group appear in the Unread column, but the font of the group name doesn't change to bold. It only becomes bold after moving the mouse over the view.
The same happens, when the marking the last unread article in a group as read, then the group name is still bold even though there are no unread articles anymore.

Reproducible: Always

Steps to Reproduce:
Click "Get New Articles in All Groups" and don't move the mouse over the group list view.

Actual Results:  
The font of the group name (of a group with unread messages) isn't bold. It only becomes bold after moving the mouse over the view.

Expected Results:  
The font of the group name should become bold immediately.
