   用户反馈：向下输入内容时顶部功能框随页面滚走。
   真实滚动发生在 window/HTML 层，但 style.css 给 .main-content 设了 overflow-y:auto
   —— 它从不内部滚动，却把 sticky 的贴靠容器变成自己 ⇒ 里面所有 position:sticky
   （.topbar、.doc-editor-header 本来就写了 sticky）全部失效。放开成 visible
   （与实际滚动行为一致，横向往 body 的 overflow-x:hidden 兜底），sticky 链才生效。
   功能框（Word=#wordToolbar / Excel=.excel-toolbar）吸在 header 正下方，
   top 由 ECR.fixTopbar 按 header 实测高度写入（header flex-wrap 换行时自适应），
   这里的 134px 只是 JS 未跑时的兜底值；z-index 低于 header(30)/topbar(40)。 */
