JQM 1.3.0: Table widget and Fixed header / footer

JQM 1.3.0: Table widget and Fixed header / footer

A simple page with a fixed header and footer and a longish table needing scrolling. 

Header & footer stay in place until you click anywhere in the table. From that point on, headers & footers behave as non fixed. Is this a wrong markup on my side, a bug in JQM or by design ?

I have made a fiddle to illustrate what I mean :  http://jsfiddle.net/wrVWQ/
