in ui.mouse.js line 117:

Iframe mouseup check - mouseup occurred in another document else if ( !event.which ) {

return this._mouseUp( event );

}

These added lines break ui.draggable on iPad (I'm using touch punch). Previously, dragging worked as expected on iPad. After adding these lines, when I touch a draggable element, draggable appears to start but then immediately stop.

Removing the lines listed above fixes the issue.

Code above is formatted incorrectly. The affected lines are:

    // Iframe mouseup check - mouseup occurred in another document
    else if ( !event.which ) {
      return this._mouseUp( event );
    }

To be clear here, you're not seeing an issue with jQuery UI itself, just that the changes made in git have broke touch punch - correct?

[johnnyshields]

I have not observed an issue on non-mobile platforms, but have not tested extensively. Regardless, touch-punch is widely used and this should be fixed before release. It's likely that these lines will impact similar mobile frameworks.

I'm not seeing this issue on iOS6 - ​http://jsfiddle.net/tj_vantoll/38UFh/.

Can you please alter my test case to show the issue you're experiencing?

[johnnyshields]

Huh I played around with it but couldn't reproduce on JS Fiddle. Bizarre...

I'll have to take deeper look at what's going on in my app, will need awhile for this.

Ok, if you can get a make reproducible test case we can investigate.
