SUMMARY

run tabpage.py example, "Tab 0" tab page won't be expanded all the time, the bug is similar to bug 511166, but I think its two bugs,because only "Tab 0" have such problem , other active page tab can be expanded.If your guys think it is duplicated with the bug 511166 ,feel free to close it. 

REPRO

1.  run uia2atk/test/samples/tabpage.py, 
2.  run accerciser, expand the item with 'page tab list' role name  from left
pane of Accerciser
3.  on sample GUI, click "Tab 1" to make it the current active tab.
4.  on sample GUI,click "Tab 0" to make it the current active tab.
