安卓4.4.2中MUI 0.90 list侧滑显示多功能列表，在list的边缘滑动会使多功能列表上的icon获得焦点，导致背景色发生改变

<ul id="OA_task_2" class="mui-table-view">  
    <li class="mui-table-view-cell">  
        <div class="mui-slider-left mui-disabled">  
            <a class="mui-btn mui-btn-blue mui-icon mui-icon-checkmarkempty"></a>  
            <a class="mui-btn mui-btn-blue mui-icon mui-icon-closeempty"></a>  
        </div>  
        <div class="mui-slider-right mui-disabled">  
            <a class="mui-btn mui-btn-blue mui-icon mui-icon-checkmarkempty"></a>  
            <a class="mui-btn mui-btn-blue mui-icon mui-icon-closeempty"></a>  
        </div>
