Bug 26127

When trying to attach a getter/setter to a native DOM property on an element, the getter/setter seems to be ignored and is never called. The original behavior is maintained. Use this simple code testcase: <div id="d"></div> <script type="text/javascript"> var o=document.getElementById("d"); o.__defineSetter__("id",function () { alert("SET"); }); o.id="test"; </script> Expected behavior: an alert saying "SET". Actual behavior: nothing. The same code works as expected in Firefox and Chrome. Similarly, attaching the getter/setter on the prototype (for example, on HTMLDivElement.prototype) fails on Safari and Chrome as well, but works as expected in Firefox.
