Occasionally, though, the viewer works at higher levels, e.g. the viewer worked properly for a moment on: https://arclight-demo.projectblacklight.org/catalog/sc0280-xmlaspace_ref811_0gi - but is not now.

maybe related to #1024?

Part of this issue could be how digital objects are created in SUL's ASpace and the EAD that is exported. May not be an issue for other institutions.
