Another argument against deprecating windowHandle is that the result of 
IAccessibleRelation::targets could return indistinguishable results.  When 
uniqueID has a per-window scope, the different output targets could have the 
same uniqueID with two different windowHandles.   

This could be a problem for both one call to targets and separate calls to 
targets on different IAccessibleRelation objects.
