Modal overlay is not removed when using Animate module

[aasiph]

Hi, Using the Animate module and setting the stack modal to true does not remove the overlay after the notice is closed.

PNotify.info({
      title: "Button Clicked",
      text:
        "You have clicked the button. You may now complete the process of reading the notice.",
      stack: {'dir1': 'down', 'firstpos1': 10, 'modal': true},
      modules: {
        Animate: {
            animate: true,
            inClass: 'zoomInLeft',
            outClass: 'zoomOutRight'
        }
      }
    });
