Wrong child id in loop

Medium Severity

In the children loop, when a child’s ContentBaseName is missing or _index, id is set from $.Title (the home page) instead of the child page’s title. Top-level section entries can share the same wrong id in home index.json, which misleads consumers of the JSON/NDJSON feed.
