When I couldn't sleep the other night, I started mocking up a zippy drag-n-drop front end for Trac, based on the snappy UI of tools like Things (working title is FasTrac).  Then, bam! Bitten by a weird, seems-like-a-bug w/ jQuery UI drag and drop.  It appears that droppables aren't discoverable by draggables if the droppable has a fixed width.  I have a hard time believing that's true, yet here I am.  I posted to the jQuery UI list, but haven't heard back yet. Any ideas?  I'm sure I'm missing something super obvious... Here's a working example illustrating the problem.
