issue with backbone + zepto in ff 3.6

gistfile1.txt

The Error:
element["insertAdjacent" + (html instanceof Element ? "Element" : "HTML")] is not a function
http://localhost:8080/scripts/zepto.js
Line 145

the zepto.js is 5ecaa (HEAD of the zepto repo)

backbone.js is 261059 (HEAD of backbone's repo)

the stack looks like..
during model intiailization in the $() handler, loading models from 
json passed from the server-side view.. calling down from Collection.add 
to a master view's listener for the collection's 'add' event.. into zepto 
via $() .. the last line of my application code before going into the 
offending part of zepto looks like:

this.$('#dishes_list').append(view.render().el);

the #dishes_list is a <ul>, to which I'm appending the content of a view (with tagName: 'li');

verified working w/o error in jquery 1.4.4

hmm. bummer. i just tested it in chrome and seems to work, but some other stuff is failing. fun!

Yea. That's one reason why Zepto is so small. Because it doesn't have to worry about cross browser support.
