[Bug 27976] [Custom]: type extensions should be available as custom tags, not only through <baseTag is="...">

OK.  Thanks for the info.

Seems worth an aside in the doc, just to clarify that for current compatibility
reasons, a native element cannot be considered a native element by the browser
if it is extended via is="".
