外层元素使用伪元素，饼图的tooltip无法触发，鼠标放到内容上没有效果

Version

5.2.1

Steps to reproduce

使用的chart：Default arrangement 我的html内容： <table> <tr> <td> <div style="height:100%;" id="div_lifechart"> </div> </td> </tr> </table>

我在元素td上加了两个css `td::before { position: absolute; top: -2px; bottom: -2px; left: 15px; width: calc(100% - 30px); content: ""; border-top: 2px solid var(--MainColor); border-bottom: 2px solid var(--MainColor); z-index: 0; }

    td::after {
        position: absolute; 
        top: 15px;
        right: -2px;
        left: -2px;
        height: calc(100% - 30px);
        content: "";
        border-right: 2px solid var(--MainColor);
        border-left: 2px solid var(--MainColor);
        z-index: 0;
    }`

加完后，发现此饼图的tooltip没有显示，注释掉 td::after 又能起作用

What is expected?

正确显示tooltip

What is actually happening?

添加td::after样式之后，tooltip不显示

**TITLE** The outer element uses pseudo elements, the tooltip of the pie chart cannot be triggered, and the mouse pointer has no effect on the content **BODY** ### Version 5.2.1 ### Steps to reproduce Chart used: Default arrangement My html content: I added two css to the element td `td::before { position: absolute; top: -2px; bottom: -2px; left: 15px; width: calc(100%-30px); content: ""; border-top: 2px solid var(--MainColor); border-bottom: 2px solid var(--MainColor); z-index: 0; } td::after { position: absolute; top: 15px; right: -2px; left: -2px; height: calc(100%-30px); content: ""; border-right: 2px solid var(--MainColor); border-left: 2px solid var(--MainColor); z-index: 0; }` After adding, I found that the tooltip of this pie chart is not displayed, commenting out td::after will work again ### What is expected? Display tooltip correctly ### What is actually happening? After adding the td::after style, the tooltip is not displayed
