IPAD 4 gen / IOS 7 fixed footer bug (1.4.2)

IPAD 4 gen / IOS 7 fixed footer bug (1.4.2)

Hi,

I was testing my webapp in one Ipad(4 gen ) and i have an unexpected behavior using a fixed toolbar in the footer, after hours looking for errors in my code I decided to look what happens with the demos of JQuery Mobile and i think i have found a bug




As you can see the toolbar/footer is no longer fixed to the bottom, and this also happens when the content of the page does not fill the entire page, in that case safari places a grey bar, but this offset still there.  

This is also happening with fullscreen fixed toolbars, it looks this is related to the footer itself.


This happens on IOS 7.1.1 and the IPAD model is  A1458

at the moment i don't have a good fix for it, any idea or quick fix will be wellcome.

And sorry for mi English, i'm spanish, if is anything you don't understand please let me know.

Regards.
