I think it's backwards to assume that querySelectorAll() works a
particular way and that's that's not what authors want and to change
the DOM in response.
There are various solutions that don't involve drastic changes to the
correspondence between the markup and the DOM, for example:
* Invoking querySelectorAll() on a wrapper element that's known not to
be a parent of the templates on the page.
* Using a selector that fails to match elements whose ancestor chain
contains a template element.
* Introducing an API querySelectorNonTemplate(). (Don't say "All" if
you don't mean *all*).
Even though XML has fallen out of favor, I think violations of the DOM
Consistency principle and features that don't work with the XHTML
serialization should be considered huge red flags indicating faulty
design.
