I just looked into this very briefly, because it still happens in production, and this is happens on redirected entities. Someone is trying to undo an edit on the entity content that was present before the entity got converted into a redirect. The root cause is us trying to "patch" a diff on undo on an redirected entity, which leaves the entity redirect in place, but also (sometimes) adds actual entity content to the content object.
