Sortable UI problem

Sortable UI problem

I am attempting to modify the sortable.js UI file and have run into a problem, that might be a possible bug or more likely me misinterpreting the code. I was playing around with the _intersectsWithSides function and at the end of the function there is an if statement with this conditional: this.floating && horizontalDirection. I noticed that the function never enters this if statement even though my elements inside the sortable element and my draggables that are connected with the sortable are both floating. It appears that the this.floating, which is declared at the top of the widget is returning false, but if I redeclare this.floating inside the function, it returns true. Anyone have any ideas on what is going on here? Thanks!
