Links posted to a category page doesn't generate a one box link

[Rhidian (Rhidian Bramley)]

If I include links to specific posts in Discourse I get a nice one box.

If I include a link to the category page though it only generates a link. e.g.

Announcements

Would it be possible to get category links to generate a nice one box?

Another possible onebox improvement for the next release @jamie.wilson

The same is true for group pages, tag pages, etc. It would be great if all of the commonly used Discourse pages Oneboxed!
