Title: More elegant fix to the scrolling problem fixed by 8b9f58e

This causes the page to set a fixed height so that if a change to an an interact changes the content height, the page will not change size and move the interact control unexpectedly. When the user scrolls up after the content height has been decreased, the page changes its height automatically to minimize the unused vertical space below the viewport.
