In that example, PHP shouldn't be deciding its own behaviour at all, it should
be following the DOM standard.
It turns out, the specification explicitly states that the return value should
be null in this case, so arguably it's a bug that PHP's implementation does
not: https://dom.spec.whatwg.org/#ref-for-dom-element-getattribute%E2%91%A0
