<div>
<pre>HTML parser should not be instantiating the custom elements inside a template element using the containing document's registry.
Instead, it should be using the registry of the inert template document:
<a href="https://html.spec.whatwg.org/#associated-inert-template-document">https://html.spec.whatwg.org/#associated-inert-template-document</a></pre>
