折叠在锚点内具有span标记的手风琴

我有一个手风琴，用于激活手风琴内容的按钮内有一个带有图标的span标签 . 通常我会使用简单的CSS来添加图标，但这是一个独特的网站，我不能使用标准技术，因为它必须嵌入 .

所以我必须添加一个span标签，并且我已经构建了大部分可用的手风琴 . 如果单击 Headers 面板链接上的任意位置，它会扩展和折叠 .

我遇到的问题是如果单击 Span 图标区域 . 它总是扩展内容区域，永远不会崩溃 . 因此，例如，如果内容区域已展开，我单击图标将其折叠，内容将折叠，但随后会再次展开 .

我有JSFiddle showing where I am and the issue I am having .

HTML

<div class="accordion">
<div class="accordion-section">
    <a class="accordion-section-title" href="#accordion-1">Panel 1 <span class="has-icon">icon</span></a>
    <div id="accordion-1" class="accordion-section-content">
        <p>Content displayed for the <b>first</b> accordion panel.</p>
    </div>
</div>
<div class="accordion-section">
    <a class="accordion-section-title" href="#accordion-2">Panel 2 <span class="has-icon">Icon</span></a>

    // Grab current anchor value
    var currentAttrValue = $(this).attr('href');
    if($(e.target).is('.active')) {

    } else {
        close_accordion_section();
        // Add active class to section title
        $(this).addClass('active');
