Fixed top banner disappears on resize

Cookie consent banner disappears when resize the window if the banner placed at top.

Current code is not properly calculating assigning the top css value:

var checkIfPopupIsClosed = debounce(function () {
      var wrapperHeight = $wrapper.outerHeight();
      if (Drupal.settings.eu_cookie_compliance.popup_position) {
        var wrapperTopProperty = parseFloat($wrapper.css('top'));
        if (wrapperTopProperty !== 0) {
          $wrapper.css('top', wrapperHeight * -1);
        }
      }
      else {
        var wrapperBottomProperty = parseFloat($wrapper.css('bottom'));
        if (wrapperBottomProperty !== 0) {
          $wrapper.css('bottom', wrapperHeight * -1);
        }
      }
    }, 50);
