ui.draggable('disable') ... Remove "stack" z-index ?

[trave]

EXAMPLE URL:

​http://trave.onai.net/systems/trave/solitaire.html (.html file attached)

Each card is assigned:

.draggable({stack:{group:'#pnlSolitaire B I', min:1}})

All cards are then:

.draggable('disable');

Certain cards are later allowed by:

.draggable('enable');

PROBLEM:

Once a card has been dragged, its Z-Index is in higher order than the rest of the pile it was part of.

ENHANCEMENT:

Would it be possible that the original Z-Index of the element be returned to its native state upon "return:true", and/or .draggable('disable'); ?
