This test ensures the correctness of Spatial Navigation (SNav) algorithm over input box. * Pre-conditions: 1) DRT support for SNav enable/disable. * Navigation steps: 1) Loads this page, focus goes to "start" automatically. 2) Focus moves away from input box in 4 different directions to neighbor nodes and back. On success, you will see a series of "PASS" messages, followed by "TEST COMPLETE". 2 4 6 8 PASS gFocusedDocument.activeElement.getAttribute("id") is "start" FAIL gFocusedDocument.activeElement.getAttribute("id") should be 8.
