stop event propagation on tab click

I have a complex angularjs application (backed by grails) and
* many routes to different controllers / views, with default route bound to "/"
* ```
<base href="/mycontext" />
``` in head tag

When someone clicks on a tab, the new tab is selected, but the event is propagated and the link resolved (href=""). In my case the link change is intercepted by routeProvider which loads the main view.
