IE10 Developer Preview: TypeError
Chrome 23 dev, Opera 12.50 internal: n/a
The spec requires IE's behavior, AFAICT:
http://dev.w3.org/2006/webapi/WebIDL/#es-attributes
If I understand correctly, the getter is being called on NodeList.prototype, which is not a platform object implementing the interface on which "length" is declared, so it should be TypeError. An incorrect exception type is also thrown for accessing XMLHttpRequest.prototype.status this way (NS_ERROR_XPC_BAD_CONVERT_JS).

This is probably tested by idlharness.js, which is probably how I found it in the first place, but I didn't confirm.
