Has anybody cracked the code to get iOS 7's startup image for web apps to work properly? If you load up a web app on iOS 7 right now (on the iPhone 5 in this example), it stretches the initial 640x1096 to fill the full 640x1136 space as the app opens. Then it reverts back down into the proper 640x1096 size as the app loads. It's not the end of the world, but it creates a bit of a distracting adjustment-jump when the app opens. Is this a bug, or is there a different way to handle apple-touch-startup-image files for web apps on iOS 7?
