<!--
This test ensures the correctness the following Spatial Navigation
(SNav) algorithm features.
1) There is no unit overflow in the Spatial Navigation algorithm while
calculating the best node candidate to move focus to. To test that this
page positions some elements 10000000 pixels far from each other (distance
that can considered large enough for most of the Web Pages on the
Internet).
2) Make sure that a best focusable candidate only gets focused
if it is visible in the current Viewport. Scroll-in-direction
is performed otherwise.
* Pre-conditions:
1) DRT support for SNav enable/disable.
* Navigation steps:
1) Loads this page, focus goes to "start" automatically.
2) Attempt to move focus down to "end. As it is too far and out of
viewport, focus change will not happen and page will be scrolled
a step down.
3) By sending an "End" keypress, page gets scrolled down to a place
where the "end" node gets visible in the viewport.
4) Step _1_ is ran again, and "end" gets focused. -->
