XF 2.1 New posts not bolding 'new posts'

[Draggiie]

The new posts widget doesn't bold the new unread posts like the forum list does.
E.g.

Spoiler: New Posts Widget

As shown all threads are the same, there is no difference between unread and read threads.

Spoiler: Forum List

Here its clear what threads are read and unread, since the unread ones are bolded.

Does anyone know how to fix this issue?

The widget doesn't track read/unread status.

The widget doesn't track read/unread status.

Do you know of a way to make it track it? Or will I need to use an add-on and or make the widget myself?

It would require some form of custom development.
