Sorry to write about multiple things concurrently, but I also hit this in 
the xqsuperschool code.  Interesting.. it's expecting document.head.querySelector so 
that it can query for metas by selector syntax.  I don't know why it needs 
to be called on document.head, when metas by definition will only 
be in head.

getConfig: function(name) {
var element;
element = document.head.querySelector("meta[name='action-cable-" + name + "']");
return element != null ? element.getAttribute("content") : void 0;
},

I have been banging my brains on it for a while.  Is there a proper place 
to add functions to document.head?  I tried adding it at the very bottom, after 
document.querySelector, and it wasn't recognizing document.head unless I 
am misinterpreting messages.

Does this need to take place after third.js has run?  No.. it doesn't, 
right?  Otherwise you wouldn't be able to define document.querySelector 
either.

thanks
Kevin
