Test Case 89 failure in UAIG test suite

Test case 89, when executed generates EVENT_OBJECT_SELECTION then
EVENT_OBJECT_STATECHANGE on  the newly selected item which is in a
multi-selectable list box. That is inconsistent with the spec.

Here is test case 89:
https://www.w3.org/WAI/PF/testharness/testcases/edit?testsuite_id=2&testcase_id=89
Here is the corresponding test file:
https://dvcs.w3.org/hg/pfwg/raw-file/default/ARIA-UAIG/1.0/tests/test-files/test89.html

Here is section 5.8.3 with single select and multi-select:
https://dvcs.w3.org/hg/pfwg/raw-file/default/ARIA-UAIG/1.0/tests/test-files/test89.html

Note: Focus is NOT on the item to be selected. I suspect this will impact
what is expected on test cases 90-92 for which test files have not been
created.
