Some pattern's methods of the desktop shortcut icons return unexpected errors(+)

For instance the Invoke.Invoke() method returns UIA_E_ELEMENTNOTAVAILABLE error, ScrollItem.ScrollIntoView() method returnsCOR_E_INVALIDOPERATION error. Some methods like SelectionItem.Select() work as expected.

It can be reproduced using Inspect Object.exe (Windows 7 Professional 64).

Any ideas? Thanks.
