The "popup" data rel attribute should be mapped to the respective ARIA attributes

[vick08]

Whenever the data-rel=popup occurs in jQuery Mobile pages, the following accessibility enhancements should be mapped:

• aria-haspopup=true, to indicate that that the href with data-rel=popup links to the popup container.
• aria-expanded=true/false, should be dynamically modified when popup is shown or hidden respectively.
  For example:

<a href="#" data-rel="popup" aria-haspopup="true" aria-expanded="false" ...>Click to pop me up

I am just a simple popup but I should read fine with screen readers!

Can you please confirm that aria-expanded attribute is being applied correctly depending on the open/close state of the popup?
