Description David Kilzer (:ddkilzer) 2014-03-05 09:49:31 PST

From <https://code.google.com/p/chromium/issues/detail?id=336317>:

Version: all (ancient WebKit bug)
OS: all

What steps will reproduce the problem?
1. Open the following URL:

data:text/html,<div id=willBeRemoved> <div> <form id=f1> <input id=in1> <img id=im1> </div> <input id=in3> <img id=im3> </div> <input id=in2> <img id=im2> <script>var f = document.getElementById('f1'); var d=document.getElementById('willBeRemoved'); d.parentNode.removeChild(d); alert('' + f['im1'] + ',' + f['im2'] + ',' + f['im3']);</script>

What is the expected output? What do you see instead?
Expected: Alert "[object HTMLImageElement],undefined,[object HTMLImageElement]" according to the standard and Firefox.
Actual: Alert "undefined,[object HTMLImageElement],undefined"
