http://test.musicbrainz.org/release/04cece30-0d85-4f42-b423-05ef362a1495 has pending edits for each track (see http://test.musicbrainz.org/release/04cece30-0d85-4f42-b423-05ef362a1495/open_edits ) but only the odd numbered tracks are highlighted. Presumably the grey background for the even-numbered tracks is overriding it.
