Block's position jumps to the beginning of the item element

[VincaShp]

Vertical carousel error. When connecting the Autoscroll Plugin and the option wrap: 'circular', an error occurs about scrolling the browser window. If the carousel block is in scope but partially closed, the block's position jumps to the beginning of the item element.

$('.jcarousel').jcarousel({
        vertical: true,
        wrap: 'circular',
        animation:1000,
        transitions: true
});
$('.jcarousel').jcarouselAutoscroll({
        interval: 1000
});
