Event handlers not preserved when appending to multiple elements

[dalangalma]

In jQuery 1.3.1, if you create a new element, attach an event handler to it, and then append it to multiple elements, all but the first copy of the element lose their event handlers. This worked in 1.2.6.

There's a demo at ​http://brh.numbera.com/experiments/browserdemos/jquery-1.3.1-append-handlers.html - I've attached a copy to this ticket.

This does seem like a regression. The 1.3.1 domManip is using the DOM cloneNode method which doesn't carry over events. In 1.2.6 it used the jQuery clone method which does.

There's an other important detail about this bug:

In 1.2.6 .append() leaves the source/prototype element intact when appending to multiple target elements...

In 1.3.1 the source/prototype element is always *moved* to the first target element...

See demo attached to ticket #4174

IMO this needs to be fixed as well
