SweetAlert2 (swal) IE11 Angular 2, Overlay showing after popup

Question

Background overlay does not disappear even after the popup only in IE11. Working fine in chrome, safari, and firefox.

      swal({
            title: 'ERROR!',
            text: 'Please check email and/or captcha',
            type: 'error',
            timer: 2000,
            showConfirmButton: false
           }).catch(swal.noop);

Solution for now: Working with no issue on IE11:

       swal({
            title: 'ERROR!',
            text: 'Please check email and/or captcha',
            type: 'error',
            timer: 2000,
            showConfirmButton: false
           }).then(() => {if (swal.isVisible() === true) {$('.swal2-container').remove() } }, () => {if (swal.isVisible() === true) { $('.swal2-container').remove() } })                     
          .catch(swal.noop);
