Reducible Tabs lose their content when no active state is set on mobile

Unlike accordions, tabs always need to have one active state set. So when all accordions of a reducible tab are closed on mobile, the tabs run into issues where it can't display its contents anymore, since no active state was found when initializing .tab().

It's probably a rare scenario, since it only happens when making the viewport bigger without a refresh. For end users, I'd imagine this would only be when switching a medium sized screen like a tablet from portrait to landscape mode.

Nevertheless, disappearing content is never a good thing..
