添加 justify-content:space-around 时 li 之前的空白

Question

我正在尝试使用 ul/li 元素创建一个选项卡，我使用了 justify-content: space-around，所以它当然会在元素之间添加空格，但是当我添加时我无法设置 li 的样式例如边框，边框是在元素上而不是在空间上添加的，所以你知道如何解决这个问题吗？

这是有效的sn-p

ul.tab1 {
    /* reset unordered list to not use default list styles */
    padding: 0;
    margin: 0;
    list-style:none;
    /* add display flex with space around and vertical centering...also stop wrap */
    display: flex;
    justify-content: space-around;
    align-items: center;
    flex-wrap: nowrap;
    border: 1px solid #8A4DEE;
    border-bottom: none;
    border-top-left-radius: 12px 12px;
    border-top-right-radius: 12px 12px;
    background-image: linear-gradient(to right, #F9F9F9 , #DDCDFD);
  }

  ul.tab1 li::before {
    padding: 0;
    margin: 0;
    content: none;
  }
  ul.tab1 li a {
    height: 51px;
    color: #8A4DEE;
    border-right: 1px solid #8A4DEE;
    border-bottom: 1px solid #8A4DEE;
    display: table-cell;
    vertical-align: middle;
    padding-right: 30px;
  }
  ul.tab1 li:first-child a {
    padding-left:20px;
  }
  ul.tab1 li:last-child a {
    padding-right:10px;
  }
  ul.tab1 li a.active {
      border-bottom: none;
  }

<ul class="tab1">
    <li><a href="#" class="tablinks active">aaaa</a></li>
    <li><a href="#" class="tablinks">bbbb</a></li>
    <li><a href="#" class="tablinks">cccc</a></li>
    <li><a href="#" class="tablinks">dddd</a></li>
                                                                
                                                                
                                                                
                                                            </ul>
