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

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

--- Comment #22 from Scott Miles <sjmiles@chromium.org> ---
And we are also prepared to accept the notion from my 'sidebar' above that
custom elements will need to take care about what context they are in before
taking action (specifically in _readyCallback_).

I'm being vague because previously I used a bad example ('img'), but I think
the bottom line is that a custom element would be advised to test
'ownerDocument.defaultView' in some cases.
