I wonder if this is related to the kludge of treating lets as vars at the top-level (bug 346749)?  The object being supplied to js_PutBlockObject is the "global" object.
That bug only deals with let declarations. Let statements aren't affected. This is more likely to be bug 361566, though I don't remember the exact reason for the failure.
