当窗口不够宽时，上下滑动会导致侧边栏抖动 #16
Description
如果窗口不够宽，窗口底部会出现横向滚动条，此时将窗口底部的横向滚动条滑动到中间，然后上下滑动页面，右侧边栏会抖动。
If the window is not wide enough, a horizontal scroll bar will appear at the bottom of the window. At this time, slide the horizontal scroll bar at the bottom of the window to the middle, then slide the page up and down, and the right sidebar will shake.
