Fix favorite display for "current" articles (#2634)

Favorite articles have, in most of the themes, a gold background to
distinguish them from the other articles. However, it can be distracting
to have such a background when reading the articles, so we should turn
them back to the "default" background when articles are opened (class
`.current`).

Bug introduced in e9ce27d8d991d7806ca2c2af7e5282279e378885
