sortable fixed position bug in webkit

In WebKit based browsers (Chrome, Safari, WebKit nightly), the two sortable lists in the right sidebar work correctly if the page is not scrolled down (scrollTop = 0). However, scrolling the page down (as viewing the main content area needs), confuses the sorting: the dragged element effects the position of the other elements relatively to the page's scroll amount. No scroll and it behaves fine, ~50 pixels and it seems to effect only elements when it's 100 pixels away from them, etc. This is the sortable() code used for that, as seen in /javascripts/lpl.lab.js

  $(".inspector_list").sortable({ 
    /* connectWith: ["ul.lpl_topics_container > .container > .encapsulate"], */
    axis: "y",
    tolerance: "pointer",
    scrollSensitivity: 600
  }); 

It works fine with FireFox and Minefield.

This seems to be limited to fixed position elements.
