In that case I think we need to add a function to the platform that
CSS-escapes a string. Because right now, writing
querySelector("#" + id)
is a total footgun unless you control the id. In particular, if you're
a library you're in trouble...

As I explained in the thread, they have quite different behavior:
getElementById takes the ID, but querySelector needs a CSS-escaped form
of the ID.
I'm happy to raise this point on www-dom if you want. Just let me know.
