💡 需求背景和解决方案
Dropdown 文档页「多层下拉菜单」示例中,鼠标 hover 打开菜单后快速从 trigger 移入 popup,可能因为 trigger
mouseleave当下的relatedTarget指向页面空白或容器而不是 popup,导致浮层误关闭并出现闪烁。本 PR 在 Popup hover 关闭逻辑中补充:
relatedTarget判断,并使用document.elementFromPoint做当前位置兜底。.t-popupclass。mousemove记录最新鼠标坐标,覆盖快速经过空白区域后进入 popup 的场景。mouseenter、卸载时清理 pending close 任务,避免旧关闭任务影响新状态。📝 更新日志
