ListViewerRefreshTest.testNoSelectionRefresh fails on Linux

Start with ListViewerRefreshTest.testNoSelectionRefresh at line 92 and compare the failing assertion with the linked Linux test results and workspace log. Investigate why the refresh leaves the selection-related value at 0 on Linux; done means the test passes on Linux without breaking the viewer refresh behavior.
