| <!-- |
| 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. --> |
