a30c2172 - UI Automation client library cannot support properties added in a future version of Windows, either in cache requests, or provide defaults for them. Therefore: catch COMError when trhing to add properties to a controlFieldCacheRequest (E.g. sizeInSet on Windows 7), and also reintroduce try blocks around some of the property fetches in UIA NVDAObject's states property, much resembling what it used to be, though still using _getUIACacheablePropertyValue.
