DOMAgent.getAccessibilityPropertiesForNode won't exist on iOS 6 and 7 remote inspector backends. It looks like our frontend will add UI and unconditionally ask for accessibility information. This will throw an exception inspecting an iOS 6 or iOS 7 device and cause issues.

I think Views/DOMNodeDetailsSidebarPanel.js should add an "_accessibilitySupported() { return !!DOMAgent.getAccessibilityPropertiesForNode; }" function, and only add the UI / refresh accessibility when it is supported.
