the issue here is when executing .clone(true) on some (see below) elements that are .sortable()

im posting it here because while its an error with ui + core, its caused on executing the clone() function, so i thought it most appropriate.

the source is pretty self explanatory.

IMPORTANT NOTES:

it happens on ie7/8 (not on chrome or ff)

at the aforementioned url, when clicking the button the code executes the clone of the sortable elements. it should be noted that initially if the element isnt touched, there is no problem caused. but once the element has been dragged, focused, etc. and the button clicked, the stack overflow error is thrown.
