::在firefox中的伪元素突然停止显示之后.适用于镀铬

Question

我有一个手风琴菜单，直到最近，它还在firefox中显示：after-psuedoelements。它仍然适用于铬。我一辈子都想不出它们为什么会像萤火虫一样消失。

：：元素几天前显示得还不错，但现在突然之间，他们决定停止工作。

如有任何帮助，我们将不胜感激。

const accordionItemHeader = document.querySelectorAll(".accordionItemHeader");
accordionItemHeader.forEach(accordionItemHeader => {

accordionItemHeader.addEventListener("click", event => {
accordionItemHeader.classList.toggle("active");

const accordionItemBody = accordionItemHeader.nextElementSibling;
if (accordionItemHeader.classList.contains("active")) {    
accordionItemBody.style.maxHeight = accordionItemBody.scrollHeight + "px";  
} else {
accordionItemBody.style.maxHeight = 0;
}
});
});

.accordion {
border-bottom: 2px solid white;
}

.accordionItemHeader {
cursor: pointer;
position: relative;
color: white;
display: flex;
align-items: center;
background-color: black;
font-size: 2rem;

.accordionItemHeader::after, .accordionItemHeader.active::after {

发现问题。伪元素中的alt文本是导致firefox出现问题的原因。
