JQM 1.2 - Min Height Improperly Set?

iOS Simulator (iPhone 4S)
iOS 6
JQM 1.2

Using the "getting started" boiler plate code below, min height for the  data-role="page" is being set to 416px, which leaves a small 4px gap at the bottom.  

Does anyone have an idea why this is happening?  How to fix it?
