The popup sign in form does not submit correctly.

PROBLEM: See subject title.

REPRO STEPS:

1. Load a page with a form popup such as the sign in code, taken from  http://jquerymobile.com/demos/1.3.0/docs/widgets/popup/:

2. Click the button to open the popup.

3. Click the Sign In button on the popup.

4. Notice that a post back did NOT happen.

5. Repeat steps 1 - 3. Notice now that the post back DID happen.

WORKAROUND: The workaround I discovered is that the popup submit button will work the first time if you have loaded a page that has a query string in the URL. For example: "http://yourpage.com/?a". Now the popup submit button will work the first time.

I believe this is a bug in the framework. Can anyone confirm????
