Uncaught TypeError: Cannot read properties of null (reading 'emit')

Issue description:
Uncaught TypeError: Cannot read properties of null (reading 'emit') error after destroying instance after onTransitionEnd event:

    slider.events.on('transitionEnd', onTransitionEnd);

    function onTransitionEnd(data) {
        if(data.displayIndex === 1) {
            slider.destroy();
        }
    }

Quickfix: wrapping the destroy in a setTimeout of 0 seconds.

Demo link/slider setting:

        slider = tns({
            container: '#slider',
            items: 7,
            axis: 'vertical',
            controls: false,
            nav: false,
            autoplay: true,
            autoplayTimeout: 1000,
            autoplayButtonOutput: false,
            speed: 1000,
        });
