Update to new style breadcrumb

By requirement, only keep horizontal breadcrumb design on both
phone and tablet platform.

Change in breadcrumb will cause testKeyboard_arrowsRootsList failed
and I found this test is wired. User should only click on tab then
focus on root item. Fix this behavior and also fix test case.
