edgePadding on vertical axis not working?

[Hangloozz]

I can't get the edgePadding working on a slider with vertical axis, if I add an edgePadding of 50 it adds whitespace on the bottom only, but slides are cut off on the height as if the slider was configurated without edgePadding. Is it possible to use edgePadding on vertical axis at all?

Settings I use:

tns({
            container: '.poster-slider',
            axis: 'vertical',
            items: 1,
            slideBy: 'page',
            swipeAngle: false,
            autoplay: false,
            speed: 400,
            navContainer: '#custom-controls-year',
            center: false,
            loop: false,
            controls: false,
            gutter: 0,
            edgePadding: 50,
            startIndex: 0,
            autoHeight: false,
        });
