QJSEngine::registerModule not respected under qml

According to these docs: https://doc.qt.io/qt-6/qjsengine.html

It is supposed to be possible to register virtual JavaScript modules that are not backed by files using QJSEngine::registerModule.

I.e something like this:

QJSValue name("Qt6");
QJSValue obj = myEngine.newObject();
obj.setProperty("name", name);
myEngine.registerModule("info", obj);

import { name } from "info";

export function getName()
{
    return name;
}

However these modules do not appear to be accessible at all from either QML or more importantly javascript files imported from QML files.

Attached is a simple test project that I would have expected to work given the above docs.
