Description
The drag helper position is incorrectly calculated when the container has overflow set to scroll. It is fine so long as the area has not been scrolled, but the further down you go, the further away from the cursor the helper is positioned. Example code:
<!DOCTYPE html PUBLIC "-W3CDTD HTML 4.01EN" "http://www.w3.org/TR/html4/strict.dtd">
<html> <head>
<script type="text/javascript" src="jquery-1.2.1.js"></script> <script type="text/javascript" src="metadata.js"></script> <script type="text/javascript" src="jqueryui/ui.mouse.js"></script> <script type="text/javascript" src="jqueryui/ui.draggable.js"></script> <script type="text/javascript" src="jqueryui/ui.draggableext.js"></script> <script type="text/javascript" src="jqueryui/ui.droppable.js"></script> <script type="text/javascript" src="jqueryui/ui.droppable.ext.js"></script> <script type="text/javascript" src="jqueryui/ui.sortable.js"></script> <script type="text/javascript">
$(document).ready( function() {
var container = $('div#container'); for( i = 0; i < 100; ++i ) {
$( '<div class="item">Item ' + i + '</div>' ).appendTo( container );
} container.sortable( { items: 'div.item' } );
});
</script> <style> div#container {
height: 100px; overflow-y: scroll;
} </style> <title></title> </head>
<body>
<p>Scroll Test</p>
<div id="container"/>
</body> </html>

Attached a fix... making helper fixed position and adjusting offsets a little seems to make it better. Attached version also has some performance tweaks.

Replying to sqrrrl:

sqrrrl, this does not seem to work as expected. I've tried your version against the test (plugin/ui/test/sortable.html), the helper is positioned at the very bottom of the page, the mouse position is not relative to where you picked the element at and the floating example doesn't work correctly anymore.
It would still be great to see a working version of your performance improvements- keep me updated!

This seems to be a fixed problem.
IMHO, it was related to broken position calculation, which comes from the core.
Before closing the ticket, I'd like to fix another problem where my new items gets smaller with when dragged.
