JQuery draggable mouse cursor offset

Question

I have draggable list elements which I'm able to drag into another list (in fact is not a list but a tree based on omnifaces / primefaces).

Problem:

I need to drag from the second list to second list (reodering element).

For this between each element of the list I have a droppable with height = 0px that I modify to 20px when my draggable overlap at this level no problem, the concern comes from the fact that when I resize the droppable, the mouse cursor shift from the draggable.

This being quite difficult to explain below picture illustrating the problem

I have tested the option cursorAt with no success if anyone have a suggestion where this shifting might come from

Use the following minimal jQuery and CSS and you should be good to go.

$("#second-list").sortable({
  axis: "y",
  handle: '.sortable-handle',
});

$(".removeNode").on("click", function() {
  $(this).closest("li").remove();
});

/* QuickReset */ * {margin: 0; box-sizing: border-box;}

.sortable {
  list-style: none;
  padding: 0;
}

.sortable li {
  display: flex;
  align-items: center;
  padding: 0.5rem;
  box-shadow: 0 1px 5px -2px rgba(0, 0, 0, 0.4);
  margin: 0.5em 0;
}

.sortable-handle {
  padding: 0.3em 0.5em;
  margin-right: 0.5em;
  cursor: ns-resize;
  color: #888;
  transition: color 0.3s, transform 0.3s;
}

.sortable-handle::before {
  content: "⋮⋮";
}

.sortable-handle:hover {
  color: #863da6;
  transform: scale(1.2);
}

.removeNode {
  margin-left: auto;
  cursor: pointer;
  user-select: none;
  border-radius: 50%;
  background: #eee;
  border: 0;
  width: 2em;
  height: 2em;
  transition: background 0.3s, transform 0.3s;
}

.removeNode:hover {
  background: #fe0306;
  color: #fff;
  transform: scale(1.2);
}

.removeNode::after {
  content: "✕"
}

.sortable li.ui-sortable-helper {
  background: #fff;
  box-shadow: inset 4px 0 0 #863da6, 0 0.1rem 0.5rem rgba(0, 0, 0, 0.3);
}

.sortable li.ui-sortable-placeholder {
  visibility: visible !important;
  background: #f0eefc;
  outline: 2px dashed #863da6;
  outline-offset: -4px;
  box-shadow: none;
}
