ionicList drag Content bug - Codepen provided

Hi,

As I just posted this on slack let make sure its tracked also here. Here is the code pen
showing that when you have ionic list with option buttons the drag content to see left side bar does not work.

When you check this in safari it seems to work, on iPhone, Chrome not working.

The sideMenuCtrl.isDraggableTarget return different values chrome/safari and thefore on chrome it does not continue when chrome eval. that this is not dragable target

function onDragX(e) {
                    if (!sideMenuCtrl.isDraggableTarget(e)) 
                        return;

                    if (getPrimaryScrollAxis(e) == 'x') {
                        sideMenuCtrl._handleDrag(e);
                        e.gesture.srcEvent.preventDefault();
                    }
                }

I just debugged it and it seems that only difference is
inside that isDragable

!e.gesture.srcEvent.defaultPrevented 

returns false

When I look at Safari where it is working the srcEvent is:

   > e.gesture.srcEvent
