Is it possible to remove this function entirely and just make the omnibox view
automatically get focus by virtue of being the only focusable child?

seems to work for chrome os and linux. dominic, would you mind testing this on
windows again?

-  // Focus the view widget first which implements accessibility for
-  // Chrome OS.  It is noop on Win. This should be removed once
-  // Chrome OS migrates to aura, which uses Views' textfield that receives
-  // focus. See crbug.com/106428.
-  NotifyAccessibilityEvent(ui::AX_EVENT_FOCUS, false);
-
-  // Then focus the native location view which implements accessibility for
-  // Windows.
   omnibox_view_->SetFocus();
 }
