jquery-mobile 1.4.1 demo not working on ie8

[AtJordi]

This is a screen capture from the popup section of the jquery mobile demo page in windows 7 in IE8. The icons are missing and all the "collapsed" content of the popup are visible, seems like the javascript is down. Any Idea?
IE8 is A grade supported: http://jquerymobile.com/gbs/1.4/
