The one huge issue with iOS 7 multitasking.

I keep waiting for this to change with each beta, but I'm afraid it isn't going to. The card views are just static screenshots. If I load a web page, then double tap the home button, the card view stays doesn't show the loading page. This goes for video and just about every app.

Is this something developers will have to implement? Or is this static screen shot all we'll ever get?
