Is there an easy and reliable way to preload tabs even if preloadTabs has been removed in Beta 12?

I NEED to make sure that document.querySelectorAll('.scroll-content')[0], document.querySelectorAll('.scroll-content')[1]… are all defined before my user enter the app.

preloadTabs has been removed in beta 12 so I guess I’m screwed, but I might be wrong. Any idea ?
