It still sounds a little bit fragile (in the sense may break easily again in the future if other static content is added), but other ideas look more complex, for example in Places views we insert an invisible element that marks the beginning of the content, and we shouldn't over-engineer for this. I guess for now it's ok, it would be nice to have a more general solution to the problem (custom elements? no idea...).

any reason to not just do:
for (let kid = .firstChild; kid; kid = kid.nextSibling)?
