Title: LPS-10739 Dropzone blueline lingers on previous dropzone 

hey Nate. I was able to track down the commit that caused this (c7e64090c7143c246894ce246e3c07d7e7e480e8). I am not sure why you chose to halt the event. When we remove it, the regression goes away. I tested this in IE9, Safari, FF and Chrome.
