[ChoiceBox] Focus not re-fired on ChoiceBox after popup is closed

Environment:

Used JAWS on Win 7 used 8u40 promoted b04

To Reproduce:

Run the HelloChoiceBox Demo
On the ChoiceBox, press space to expand
Using the arrow keys try changing the focused item
Selection Changes are read by the screenreader as they happen as Hans Solo, Leia Organa etc.,
Try selecting a specific item using space bar or Enter key, now JAWS reads as "Space, Graphics 73" for all the selections.

Graphics 73 is unrelated, not sure where JAWS is reading from.
