Fuck this solution!

        removeOptionFocuses: function() {
            var interval =  setInterval(function() {
                var ulElement = getDomNode(this.view.segDataKA).querySelectorAll('ul > li');

                if (ulElement && ulElement.length) {
                    Array.from(getDomNode(this.view.segDataKA).querySelectorAll('ul > li div[tabindex]')).forEach(function(li) {
                        li.setAttribute('tabIndex', '-1');
                     });

                     clearInterval(interval);
                }

            }.bind(this), 100);
        },
