What happened?

picker组件在触摸屏笔记本电脑（华为某款自带触摸屏的笔记本电脑）上无法拖动，在pc浏览器浏览文档时，picker也不能拖动。用手在触摸屏上滑动去拖就可以。不带触摸屏的笔记本电脑可以用鼠标拖动，移动端的浏览器中使用也正常。

Research direction
The bug involves touch and mouse event handling discrepancy on touchscreen laptops. Investigate the picker component's event listeners in the source code, likely in src/components/picker. Look for how it handles 'touchstart', 'touchmove', 'touchend' vs 'mousedown', 'mousemove', 'mouseup'. Check if there is a missing pointer events polyfill or if the component only listens to mouse events. Also consider the difference between click and drag behavior. The issue may require adding pointer event listeners or ensuring touch events are not blocked.
