#4303 incorrectly resolved as invalid
#4303: (sortable: receive: ui.item references the source element)
The point of the bug report is that now there is no way to manipulate
the dropped element via the ui object in the receive handler. This is
a breaking change and quite problematic for some use cases.
If ui.item is not supposed to reference the new item (it used to) we
need a new property that satisfies this requirement. Better sooner
than later... Thanks!
