Description
Steps to reproduce:
1) Run org.apache.pivot.wtk.test.ContextMenuTest
2) Right-click to bring up the context menu, and select "Help->About" (nothing will happen, which is expected)
3) Right-click to bring up the context menu again...
Result:
1) "Help" is still highlighted, when it shouldn't be
2) If you try to keyboard navigate the menus, you can't navigate to or past "Help". Further, "Help" remains highlighted while you highlight other nodes, leading to two concurrently highlighted menu items.
