/* 1. 剥夺外层 <a> 标签的渲染权限 */
#msupload-select .oo-ui-buttonElement-button {
    background-image: none !important;
    -webkit-mask-image: none !important;
    mask-image: none !important;
}

/* 2. 剥夺可能存在的伪元素渲染 */
#msupload-select .oo-ui-buttonElement-button::before,
#msupload-select .oo-ui-buttonElement-button::after {
    content: none !important;
    display: none !important;

/* 3. 保护内层真正的图标 <span> */
/* 确保只有它能触发 Citizen 的 mask-image 逻辑 */

    display: block !important;
    -webkit-mask-size: contain !important;
    mask-size: contain !important;
    background-color: currentColor !important; /* 维持 Citizen 的图标染色逻辑 */

/* 4. 修复高度对齐（防止图标飞出去） */

    display: flex !important;
    align-items: center;
