When

.delegate

is set on a node, and the node or one of its ancestors is cloned with

.clone(true)

, in jQuery 1.7 the delegate's object filter is not conserved and the delegate is transformed in a normal "click" event.

(in both test cases, top table is original and bottom table is cloned one)

1.6.4, correct behavior http://jsfiddle.net/DFv8F/

• clicking on "head" cell prints "row" in both tables
• clicking on any "cell" cell prints "cell" in both tables
• clicking on "last" cell prints "last" in both tables

1.7.1, incorrect behavior http://jsfiddle.net/DFv8F/1/

• first table (original) behaves as above
• second table (clone) prints all of "last", "cell" and "row" when clicking on any of the table's cells.

note: adding a second

true

to

.clone

has no effect (and no reason to have any, since we're only losing metadata not the events themselves)
