Subject: [PATCH] Bug 25031: (QA follow-up) Avoid displaying extra navigation

This patch reworks the construction of the navigation links in such a
way that they are built during a loop over an updated jQuery object.
Previously the stored variable might not reflect that some elements
had been removed.
