Change #1023979 had a related patch set uploaded (by TK-999; author: TK-999):

[mediawiki/core@master] Allow interwiki redirects on the same domain

This is a headache for sites that host sister projects under the same domain:

https://starwars.fandom.com/wiki/essences:Test works as expected,
https://starwars.fandom.com/wiki/es:Test only works thanks to a bag of tricks involving hijacking the BadTitleError thrown from the init code to serve a redirect anyways.

The limitation seems to be unnecessary and can probably be removed.

Boldly tagging Mediawiki-Platform-Team since the component is without an owner but the change should be very simple.
