If I from javascript remove a input-element with removeChild and immedialy insert the element the same place in the DOM-tree and set focus to the element again, the onchange event is fired. Even through nothing is changed in the input.

Reproducible: Always

Steps to Reproduce:
1.Look at the submitted example, the example is an input with a onchange event and     a script to remove the input and put it back in the DOM tree.
2.Click in the input field
3.Now the script to remove the input is triggered, and input is set back to the DOM-tree and focus is given to the input element.
Actual Results:  
The onchange event is fired for the input field, even through nothing is changed

Expected Results:  
No onchange event expected

Seems to work correctly with Firefox 3.6 and current trunk (4.0).
