Vincent Petry e2549fa660 Improve right sidebar tabs behavior
Tab heads are not rendered if only one tab.

The tab contents is updated on-demand. This means that if a tab is not
visible it is not rendered at first. If the tab was already rendered
through switching, its model will not get updated until the next time it
becomes visible. This will prevent needless rerendering of invisible tab
contents, especially considering that some tabs might need extra ajax
requests.
