Problem connecting horizontal and vertical sortable ul's

Problem connecting horizontal and vertical sortable ul's

I discovered a problem when connecting a normal vertical sortable ul to a horizontal (float: left) sortable ul.

With the vertical one everything works fine, but the horizontal one uses mouse events if it were a vertical one. So when I'm trying to drag an item to the right in the horizontal ul, the mouse pointer has to be below the middle of the item. When dragging to the left the mouse pointer has to be above the middle of the item. This makes the behavior of dragging in the horizontal ul acting very odd.

Is there a way for me to fix this problem of should I submit a bug report?

Thanks in advance,
Ruud


Edit:
I think i also found the cause of the problem, which would be at this line in jquery.ui.sortable.js:
  1. this.floating = this.items.length ? (/left|right/).test(this.items[0].item.css('float')) : false;
This line looks at the float property of the first item. But when connecting multiple sortables, the first item could be an item of another sortable (which doesn't has to be floated).
