‘게시물 수정’에서 취소한 후에도 게시물을 해제할 수 없음

In our site, Discourse.SiteSettings.reviewable_claiming is set to False (so the frontend does not show any claim/unclaim button). However, when I click ‘Revise post’, the whole topic is automatically claimed by me. In such case, can the topic still be able to be unclaimed when your MR is merged and takes effect?
