Hi tjvantoli. I understand your guidelines. I signed the CLA and it is a minor patch that fixes a well known bug open for 3 years (http://bugs.jqueryui.com/ticket/7098). The code follows your style guide, but I do not have time to become a full developer. I hope someone can deal with it properly instead of throwing the patch away.
