templates aren't decorated until DOMContentLoaded and may be used before then

[rafaelw]

e.g.

<template id=test bind>
<table>
  <tr template repeat><td>{{}}</td></tr>
</table>
</template>
<script>
document.getElementById('test').model = [0, 1, 2]
</script>

If there are native templates, the outer template will be instantiated, but the inner semantic hasn't been decorated and doesn't get its content lifted in time.

Without native templates, nothing much interesting happens (neither template is decorated in time).

With mutation observers, we could observer during parse, but I'm not sure what to do with them. Arv?

Observing during parse will handle some more cases but not all. I'm not sure there is a good solution here.

This will need to simply be documented as a sharp-edge of the polyfill.
