Embedding Json in Scalate

I want to embed JSON in the DOM as outlined in the below question:

Best practice for embedding arbitrary JSON in the DOM?

However I can't figure out how to do this with Scalate/Scalatra. I have this in my scaml template:

-@ val fullStateJson: String 

and I can render it via

%div= fullStateJson 

but I can't figure out how to get this into a <script>. When I do

%script(type="application/json" id="fullStateScript") =fullStateJson 

It ends up escaped, like

{"45":{"id":45,"level":0},"98":{"id":98,"level":0}}
