When submitting an edit to remove the specific ordering attribute of a work that has medley relationships with "These relationships have a specific ordering" ticked, the edit is not submitted or applied at all.

This behavior can be seen here: https://musicbrainz.org/work/8d38efe0-6c58-4626-b052-8dd80e67ae61 (These works actually don't have a specific ordering in the medley, and it's not been possible to remove the attribute.)
