Top Bar scrolls entire content window on iOS

Maybe this is just a simple mistake or over-looking of the API specs but I’m unsure how to handle this. All of the Ionic Framework apps I’ve tested currently available in the App Store do not have this issue.

Do you mind providing a codepen showing this issue?
