When reordering art in a release like http://test.musicbrainz.org/release/5e0fa610-ec47-4c2d-a92a-08cf842b76e2/reorder-cover-art the last image's thumbnail keeps changing to the same as other images (seemingly all in the top row) each time I move an image. I have no idea what's going on but it's very confusing (clicking it still opens a popup with the right image, so that's OK)
