Issue: Imported MediaWiki Redirect with anchor ignores hash

After importing a MediaWiki instance I noticed on a page redirect where the target link includes an anchor (to link to a specific part of a page), the hash is ignored.

I see there is already support for anchor linking on the synonym edit screen, so this doesn't sound too big of a deal to fix? Nevertheless there are just a few of these kinds of imported redirect pages on my wiki so it that much of a hassle to update them manually for the time being.

You may refer to the annotated screenshot (attached) for a clearer idea.
