There is no ability to trigger custom scroll from Sortable if scroll container has overflow: hidden property

[IgorLav]

Problem:

There is no ability to trigger a custom scroll from SortableJS if the scroll container has overflow: hidden property.
Most of custom scroll plugin use overflow hidden for scroll container, to prevent showing native scrollbar and display custom one.
The following code prevents triggering on scrollCallback. Please, add a check of overflow: hidden
if there is !winScroller;

if (el === winScroller) {
...
} else {
canScrollX = width < scrollWidth && (elCSS.overflowX === 'auto' || elCSS.overflowX === 'scroll');
canScrollY = height < scrollHeight && (elCSS.overflowY === 'auto' || elCSS.overflowY === 'scroll');
}
