Re: [webcomponents] Should HTML parser instantiate custom elements inside a template element? (#406)

This should be fixed by https://github.com/w3c/webcomponents/commit/58a2f7b6d1853b92001b5651228a8177447a7cb3 which gives template contents owner documents a null registry, so `defineElement` will throw on them, and the HTML parser will never instantiate them.
