scrollMode: go.Diagram.InfiniteScroll Infinite rolling problem

Hello
Enable infinite scrolling. Can scroll bars be displayed when zooming?
scale:1,
minScale:0.15,
maxScale:3.0,
allowZoom: true,
scrollMode: go.Diagram.InfiniteScroll,

Scroll bars are somewhat meaningless when scrolling infinitely. Perhaps you want to set Diagram.scrollMargin to a large value instead of setting scrollMode?
