This is implementor feedback on
http://www.w3.org/TR/webmessaging/#event-definitions
See https://www.w3.org/Bugs/Public/show_bug.cgi?id=23176
Note that there is no coverage of the behavior here in the test suite,
apparently, so Blink's implementation doesn't match what the spec
currently has at all, and doesn't so much match sanity. For example, this:
var a = new MessageChannel();
var b = new MessageEvent('message', { ports: [a.port1, a.port2] });
alert(b.ports == b.ports);
alerts false in Blink. I can't check in IE because in IE10 the
MessageEvent constructor throws when called as above and in IE9 there is
no MessageChannel.
In any case, this section of the spec needs fixing and tests...
