Sortable: clicking on item doesn't unfocus focused control

Sortable: clicking on item doesn't unfocus focused control

By default, when user left-clicks outside a form control, the currently focused control (if any) loses focus, possibly triggering change event.

This does not happen when the element clicked is an item of a ui.sortable.

Note very, very well: the click() handler attached to the sortable item, if any, does get called. Only the default behavior (unfocusing the focused control) is suppressed.
