Memory Leak in IE8 when using custom events

[[email protected]…]

I'm seeing a memory leak in IE8/7 when binding custom events to a Jquery DOM object which is referenced in a JS object. IE9 seems fine. Using a standard event ('click') works fine as well.

Full code at ​http://jsfiddle.net/hah8n/1/

var testField = function ($in) {
  var $input = $in;
  var onCustom = function () { }

  this.Test = function () {
    $input.on('custom', onCustom);
  }
}

var $input = $("<span>" + Math.random() + "</span>").appendTo($row);
new testField($input).Test();

In the JSFiddle I also added clean-up code as a solution maybe - but it doesn't help. Also storing all instances of "testField" somewhere and then later deleting them (using "delete" command) did not help.

Any ideas, maybe some insights on custom events and special treatment in IE8?

Can you try with 1.8b2 and see if the problem has been fixed?
