It seems the recording section in the new relationship editor is more happy to expand to fit long relationships (in the example image, there's a relationship to "St. Edward the Confessor's Church in Mottingham, Bromley, Lewisham, Greenwich, London, England, United Kingdom" further below), which is not bad in itself but it feels a bit much in this case. Compare how little space is left for the works column in beta (above) vs prod (below) in the image - beta even wraps the "Add another artist" lines.
