可滚动div中的滚动条不会一直延伸到底部/右侧

I have a larger div contained within a smaller one; I'm enabling scrolling over the width and height of the internal div using overflow: auto on the outer div. However, in Chrome the scrollbars that appear never scroll all the way to the right/bottom edges, instead, they only ever fully touch the top/left edges. Is there a way to adjust their position to make them more centered and reach all the way to the bottom/right, or to have them not extend as far to the top/left?I have a larger div contained within a smaller
