Cosmetic bug: a.link-group:visited in groups list has same colour whether subscribed or unsubscribed

See this image.

Which groups are unsubscribed? All of the ~sports.X groups are unsubscribed, but american_football, basketball, football, and motorsports have been visited.

The link-visited colour set by a.link-group:visited is taking precedence over the default colour otherwise set by .group-list-item-not-subscribed a.link-group, hiding the colour change associated with -not-subscribed. This is particularly troublesome when unsubscribing from a group, since one must go to the group's page – visiting the link – in order to unsubscribe.
