When navigating between menus, new nav is also re-loaded ( minor issue)

[nithyaasworld]

When navigating between menus, new nav is also re-loaded. You can see that the nav bar flickered once, when navigating between menus.

Expectation: Nav bar should not get re-loaded. Nav bar should not flicker.

@luizrrodrigues this needs attention.
It is related to href property in menu item object of the menu tree. If it is null/undefined link won't redirect and menu won't reload. I tested such behavior but navi throws error when href is undefined. Please, add a check for href === undefined when the active path is determined.
Thanks

@kkartunov I think is not problem with href, page not reload just the animation of new nav.
