Description Jungkee Song 2013-02-22 01:32:18 PST
Steps to reproduce:

ProgressEvent CR (http://www.w3.org/TR/progress-events/) test
- Test wiki: http://www.w3.org/wiki/Webapps/Interop/ProgressEvents
- Test suite: http://w3c-test.org/webapps/ProgressEvents/tests/
- Test case: http://w3c-test.org/webapps/ProgressEvents/tests/submissions/Ms2ger/interface.html
(3)(4)(5) The ProgressEvent interface 1, 2, 3


Actual results:

Test case failed: 
var desc = Object.getOwnPropertyDescriptor(ProgressEvent.prototype, a[1])
returns undefined such that desc.enumerable and desc.configurable cannot be checked.


Expected results:

var desc = Object.getOwnPropertyDescriptor(ProgressEvent.prototype, a[1])
successfully returns descriptor and results decs.enumerable === true and decs.configurable === true
