An attempt to batch-add relationships for this release causes a JavaScript exceptions in both Chrome and Firefox:
https://musicbrainz.org/release/54dff9a7-382c-482f-862e-12385d0b35a7
To reproduce: open a release, click on “Edit relationships” in the right column. In both Chrome and Firefox I see a “loading” animation which does not stop. If developer console is opened with F12, it shows some JavaScript exceptions.
If this forum is a wrong place to report such errors, where should they be reported?
