JQM 1.3b1 input causes fixed toolbars to break iOS 5.1.1

JQM 1.3b1 input causes fixed toolbars to break iOS 5.1.1

When bluring an input (typing something and then clicking away or "done" in the keyboard, fixed header and footer go to the top and bottom of the page, rather than coming back to a fixed position.

This didn't happen in iOS before. It happened only in android.

The problems appear to be in line 10610 where the show() method of the toolbars will only execute if self._visible, which is false

(shouldn't it execute if the toolbar is invisible?)
