REPRO:
1. run uia2atk/test/samples/combobox_dropdown.py 
2. run accerciser, expand ComboBox and select the menu item whose Name is "0" and Rolename is "menu item",  check the list of states in Accerciser's interface viewer.
3. on Gui, in drop down the combobox and select "0" 
4. check the list of states in Accerciser's interface viewer.

RESULTS:

step 2: the state = ['enabled','selectable','sensitive','visible',]
step 4: the state = ['enabled','selectable','sensitive','visible','focused', 'selected', 'showing' ]

EXPECTED RESULTS:

step 2: the state = ['enabled','sectable','sensitive','visible','focusable']
step 4: the state = ['enabled','selectable','sensitive','visible','focusable', 'focused', 'selected', 'showing' ]

COMMENTS:
for the step 2 and 4 , I hope 'focusable' in the state list.
