Certain wiki pages are redirects to a specific section of another article. For example, [[Web 1.0]] redirects to [[Web 2.0#Web 1.0]].
However, the content service doesn't seem to preserve the section (fragment) of the redirect link:
The MediaWiki API propagates this as a tofragment parameter in its response. Therefore, ideally the content service should also pass the fragment through in a similar way.
