Issue #3542159 by tom konda: The elementSettings property assignment is...

      // This class means to submit the form to the action using Ajax.

          // normal form action.

        elementSettings.url = $(el.form).attr('action');

          url: $(el.form).attr('action'),

          // Form submit button clicks need to tell the form what was clicked so

          // it gets passed in the POST request.

        elementSettings.setClick = true;

          setClick: true,

          // Form buttons use the 'click' event rather than mousedown.

        elementSettings.event = 'click';

          event: 'click',

          // Clicked form buttons look better with the throbber than the progress

          // bar.

        elementSettings.progress = { type: 'throbber' };
