``` It shows a top divider after scrolling if it is not the first child in its parent container, indicating there is more content above. It shows a bottom divider if it is scrollable and it is not the last child in its parent container, indicating there is more content below. The bottom divider is hidden if it is scrolled to the bottom. If `paper-dialog-scrollable` is not a direct child of the element implementing `PaperDialogBehavior`, remember to set the `dialogElement`: ```html
