webcontainer simply displays "html" (instead of text-attribute)

is this a jasonette-web limitation?
afaik as i know this could be something like:

```
var doc = document.createElement('iframe')
doc.open();
doc.write(inlinehtmlAsString);
doc.close();
document.body.appendChild(doc)
```

ps. if webcontainer is already working please provide example-link
