Web Inspector: expose orientation values (sliders, scrollbars, etc) aria-orientation has different default values depending on the role, so it will be useful to have this in the inspector b/c it's frequently not exposed in the DOM. We might also be able to detect (and warn) if this value did not align with rendered views (e.g. height > width conflicts with horizontal orientation, or vice versa)
