Css 悬停时可展开的按钮与屏幕右侧对齐，如何保持未悬停的按钮正确对齐

我有一个工作代码，当用户悬停在 map 上时，它会展开按钮.我的问题是，当用户将鼠标悬停在右侧的按钮上时，它也会移动所有其他按钮.我不确定我错过了什么.在这里，您可以看到问题: https://jsfiddle.net/qjwtum3c/2/个

    .extendable-button-container-right {
      position: absolute;
      top: 20px; /* Adjust top position */
      right: 20px;
      z-index: 1000;
    }


    .extendable-button-right {
      background-color: #0d6efd;
      color: white;
      padding: 10px;
      border: none;
      border-radius: 4px;
      cursor: pointer;
      transition: all 0.3s ease;
      display: flex;
      align-items: center;
      margin-bottom: 10px;
      box-shadow: 4px 4px 4px rgba(0, 0, 0, 0.5); /* Add shadow effect */
