jQuery Mobile 1.2 loading message problem

jQuery Mobile 1.2 loading message problem

Based on JQuery Mobile 1.2 spec, I used $.mobile.loading('show') method to display wait spinner whenever user tap on listview.  My list items were displayed in full mobile screen.  It works fine except two items positioned within the area the loading message WILL be displayed.  Seems the loading message block the tap event.  However if I click once more on the item, it works fine.  

Anyone encounter this case?
