Touch screen mode optimization suggestions

触屏模式下，双指拖动设置为鼠标滚轮，滚动时鼠标左键被按住的状态，总会选中一些内容，有些列表甚至会误触跳转到其他页面。希望能在双指滚轮模式时取消鼠标左键按压状态。

Google Translate:
> In touch screen mode, two-finger drag is set as the mouse wheel. When the left mouse button is held down during scrolling, some content will always be selected, and some lists will even jump to other pages by mistake. I hope to cancel the left mouse button press state in two-finger wheel mode.
