EDIT: it also only seems to happen if the camera icon is on one of your Home Screen pages. I haven’t been able to reproduce the behavior when swiping across the icon while in the App Library. Wonder why they decided to do it that way? Do most people keep a camera icon on their Home Screen? That would be baffling to me. Why clutter your Home Screen when you can so easily access the camera from the lock screen or by using the physical camera button on newer iPhones?
