[bug] revertOnSpill won't work when swap:true

[aca14rh]

this.sortable = Sortable.create(el, {
           revertOnSpill: true, 
           swap: true,
           swapClass: "highlight",
...

hi, I attemp to use both swap and onspill plugin, but the swap works as expected, but it wont revert when spill, is this two plugin conflicts? is there any method to make it work?
