[Bug 21485] [Custom]: Consider possible candidates of element upgrade

https://www.w3.org/Bugs/Public/show_bug.cgi?id=21485

--- Comment #20 from Rafael Weinstein <rafaelw@chromium.org> ---
Also, WRT To <template> contents, the question arises: should template contents
also be upgraded?

Given that <template> is the primitive for expressing prototypes of DOM
fragments -- and script is very likely to interact with those elements, the
desirability of a strong guarantee about custom element upgrade necessarily
extends to template contents.

At worst, the upgrade algorithm
(https://dvcs.w3.org/hg/webcomponents/raw-file/tip/spec/custom/index.html#dfn-element-upgrade)
to should upgrade all elements which are a host-including inclusive ancestor
(http://dom.spec.whatwg.org/#concept-tree-host-including-inclusive-ancestor) of
the document.
