JQM 1.2 Popup scrolls to top of page when closed - on iPad/iPhone

JQM 1.2 Popup scrolls to top of page when closed - on iPad/iPhone

I'm trying to use the new Popup feature in JQM 1.2. On iPhone/iPad (not desktop and didn't try other mobile devices), if the popup link is down the page so the screen has scrolled, then closing the popup causes the screen to scroll back to the top.

Below is the code I used for testing. It has a "page1" which is a one-item menu and a "page2" which has a bunch of text with a popup link near the bottom. Again, this works fine on a desktop, but the page scrolls to the top on closing the popup when tried on an iPhone/iPad. Any help would be appreciated.
