ご報告です。

めっちゃ微調整ですけれども、Bookmarklet 使えなくなっていたので更新しました。

javascript: {
   const AMAZON_AFFILIATE_ID='cluboshiire-22'
 
   // 書籍名の取得
   const productTitle = document.getElementById("productTitle");
   const ebooksProductTitle = document.getElementById("ebooksProductTitle");
   const title = productTitle ? productTitle.innerText.trim() : ebooksProductTitle.innerText.trim();
 
   // ASIN の取得
   const asinId = document.getElementById('ASIN'); 
   const asin = asinId ? asinId.value : document.getElementsByName('ASIN.0')[0].value;
 
   //登録情報欄を取得
   let detail = document.getElementById('detailBullets_feature_div');
   if (!detail) {
     const subdoc = document.getElementById("product-description-iframe").contentWindow.document;
     detail = subdoc.getElementById("detailBullets_feature_div");
   }
 
   // 出版関係の情報を取得 (ここでは出版日付だけ)
   const pubdata = detail.innerText.split(/\n/);
   const publish_date = pubdata[2].slice(10);  //出版日付
 
   // 書籍のタイトルとリンク貼り
   const url = `https://www.amazon.co.jp/exec/obidos/ASIN/${asin}/${AMAZON_AFFILIATE_ID}`;
   const link = `[${title}](${url})`;
 
   // 選択範囲を取得する
   const isSelection = window.getSelection().toString();
   const selection = isSelection ? `> [!quote] ${title}\n> ${isSelection.replace(/(\W+)( )(\W+)/g,'$1$3').replace(/\n/g,'\n> ')}` : "";
 
   // 書影の取得
   // const imgBlkFront = document.getElementById("imgBlkFront");
   // const ebooksImgBlkFront = document.getElementById("ebooksImgBlkFront");
   //   const imageurl = imgBlkFront ? imgBlkFront.getAttribute("src") : ebooksImgBlkFront.getAttribute("src");
   const imageurl = document.getElementById("landingImage").getAttribute("src");
   // update at 2023/11/17
   const mdimage = `\n![|100](${imageurl})\n`;  
   
   // 著者情報の取得
   const authors = [];
   const viewAuthors = [];
   document.querySelectorAll('.author').forEach((c) => {
       var at = c.innerText.replace(/\r?\n/g, '').replace(/,/, '');
       var pu = at.match(/\(.+\)/);
       var ct = at.replace(/\(.+\)/, '').replace(/ /g, '');
       viewAuthors.push(`[[${ct}]]${pu}`);
       authors.push(ct);
   });
 
   // 表示する内容
   const lines = `---\ntitle: ${title} \nauthor: [${authors.join(',')}]\nasin: ${asin}\npublish_date: ${publish_date}\ncategory: \n---\n# ${link}\n${viewAuthors.join('\n')}${mdimage}\n${selection}\n\n----\n`;
   
   document.getElementById('bookDescription_feature_div').innerHTML = `<textarea style="height:500px">${lines}</textarea>`;
 }

BEFORE

document.getElementById('productDescription_feature_div')

AFTER

document.getElementById('bookDescription_feature_div')

たまにこういう微調整くるからしんどいっすね。
