[Bug 20913] [Custom]: What does inheriting from existing HTML element really mean?

https://www.w3.org/Bugs/Public/show_bug.cgi?id=20913

--- Comment #33 from Dimitri Glazkov <dglazkov@chromium.org> ---
One upside of the solution, outlined in
https://www.w3.org/Bugs/Public/show_bug.cgi?id=20913#c9 is that a custom
element is guaranteed to have the right platform (C++) object, even before its
definition was registered.

Given that, the effect of the element upgrade process (when an element's
definition is registered) can be viewed as only mutating the prototype chain.
