pub(crate) fn find_window_proxy_by_name(
&self,
name: &DOMString,
) -> Option<DomRoot<WindowProxy>> {
for (_, proxy) in self.map.borrow().iter() {
if proxy.get_name() == *name {
return Some(DomRoot::from_ref(&**proxy));
}
}
None
}
has no defined search order, so any window proxies with duplicate names can yield unexpected behaviour for automated tests.

The spec defines an algorithm for looking up target navigables by name, which we need to implement: https://html.spec.whatwg.org/multipage/document-sequences.html#find-a-navigable-by-target-name
