Story 8532 - New auto-scroll on 804 drawer module

Test auto-scroll for 804 module:

1) Scroll to where the button is at bottom of screen, then click.  Screen should scroll upward, to where as many drawer links as possible are visible -but no further than will show the sticky In-Page Nav, plus top of drawer button. The button should also center on screen when auto-scrolled.

2) Scroll to where first line of drawer links would appear when the button is clicked, then click.  There should be no scroll, because the visitor can see the action created by the button click.
