Here is a work around with result, http://take.ms/4VUaq
<!doctype html>
<html class="no-js" lang="en">
<head>
<style>
h1, h2, h3 {
color: red;
}
</style>
<template>
<h2>h2</h2>
</template>
</head>
<body>
<h1>h1</h1>
<div id="host"></div>
<script>
var template = document.querySelector('template');
var clone = document.importNode(template.content, true);
var host = document.querySelector('#host');
var shadow = host.createShadowRoot();
shadow.appendChild(clone);
var h3 = document.createElement('h3');
h3.textContent = 'h3';
shadow.appendChild(h3);
</script>
</body>
</html>
In conclusion, you definitely can't query elements from template's script except put DOM entites inside shadow hole.
