Problem with touch devices and links

Hi, great library, works perfectly when used on pcs with the mouse. On touch devices like iPad or Android I experienced a problem though:
I've got the following markup:
ul
li
a href=xyz
Sorting items by dragging works perfectly, but clicking on the links has no effect.

I tried this patch: https://github.com/johnny/jquery-sortable/pull/169 but it isn't perfect either. Clicking on links works with this page, also the dragging works, but when dropping the link is clicked instead of firing the onDrop event.

Any idea?
