Draggable + Sortable & Scrollable Divs

I have a container with a list of items to be dragged and a container with a list of items to be sorted. Draggable and sortable list are connected, which allows the user to drag and drop clones of dragged objects into the sorted list.

Dragable items are displayed in a vertical list, however, items to be sorted are displayed in a horizontal list, achieved by floating them to the left. The container of items to be sorted has an overflow set to auto, which results in a horizontal scrollbar if the content is full. Two containers are displayed next to each other, dragged to the left and sorted to the right.

The problem I ran into is when the container of sorted items scrolls to the right, dragging from the draggables container immediately triggers sorting events. It seems that the contents of the sortables container are moving beyond the draggables container.

Here is my code:

        $(function() {
            $("#sortable").sortable({
                start: function(event, ui) {
                    if (ui.helper !== null) console.log("sortable \"" + ui.helper.text() + "\" drag start");
                },
                stop: function(event, ui) {
                    if (ui.helper !== null) console.log("sortable \"" + ui.helper.text() + "\" drag stopped");
                    if (ui.item !== null) console.log("sortable item \"" + ui.item.text() + "\" drag stopped");
                }
            });

            $("#sortable").sortable("disable");

            $("#draggable li").draggable({
                connectToSortable: '#sortable',
                helper: 'clone',
                revert: 'invalid',
                cursor: "default",
                cursorAt: { top: -5, left: -5 },
                start: function(event, ui) {
                    if (ui.helper !== null) console.log("draggable \"" + ui.helper.text() + "\" drag start");

            </ul>
        </div>
    </form>
</body>

How can I avoid sorting events to trigger until the item is dragged along the sortable container?

Thank you in advance

It has been a long time since I posted this question, and since then new versions of jQuery and jQuery UI have been released.
