Uncaught TypeError when calling $.extend on a click event object

Description
I'm capturing mouse clicks on my page by binding the click event of the body element. I'm wrapping up information about the event and storing it as JSON, using $.extend to perform a deep copy of the event object.
If I click an input element (in my case a radio button), $.extend then loops through the click event object and gets this error: Uncaught TypeError: Accessing selectionEnd on an input element that cannot have a selection.
I've attached a quick and dirty example based off what I'm doing:
$("body").click(function(eventData) {
var click = {
X: eventData.pageX,
Y: eventData.pageY,
timestamp: (new Date).getTime(),
target: $.extend(true, {}, eventData.target)
};
});
<html><body><form><input type="radio"></form></body></html>

You should not be using $.extend on a node. It is meant for merging plain objects and nodes cannot always be treated as such. To make copies of nodes, use http://api.jquery.com/clone/
