In Index Designer I create a keyword, click Properties, and
select a different keyword from the list to cross reference it to.
The lower pane correctly displays the cross ref info.
In the saved, generated WebHelp, I expect to see and click
"lifecycle models" and the index should jump to "models". However,
the new keyword isn't even displayed. Adding a subkeyword causes
the new keyword to display, so keyword entry seems to work fine.
