michael@0	9	* A test to ensure that when an input field is focused, it is not obscured by the VKB.
michael@0	10	* - Loads a page with an input field past the bottom of the visible area.
michael@0	11	* - scrolls down to make the input field visible at the bottom of the screen.
michael@0	12	* - taps on the input field to bring up the VKB
michael@0	13	* - verifies that the input field is still visible.
