What would happen if you move by character from the space after the "a"? 
Would you get "f" or "foo"? And what will pressing right arrow when 
using browser caret navigation (including contentEditable) do? These are 
the sort of questions that make techniques like this very problematic. 
The answers to these questions need to be well defined.

If UIA is really mapping this to the text pattern alone, it could be 
argued that IA2 should actually do the same; i.e. don't expose an 
accessible, just expose it in IAccessibleText. However, see the above 
potential gotchas.
