The cause is actually a mistake in the Manifest: It uses the illegal image/jpg MIME type for the JPEG image on the Canvas annotations. The MIME type for JPEG is image/jpeg with an e, and this is what the code checks against.
@ch-sander are you in control of the icat.digitaldogsbody.net IIIF server?

Mike Bennett is. I will share this with him. Thanks for pointing out that issue.
