Description

To show the redirects to a title you can use the link:

https://de.wikipedia.org/w/index.php?title=Special:WhatLinksHere/Berlin&hidelinks=1

For the article [[de:Berlin]] the following 4 redirects exist:

[[de:Land Berlin]]
[[de:DE-BE]]
[[de:Freie Hansestadt Berlin]]
[[de:Stadt Berlin]]

The API has the following query:

https://de.wikipedia.org/w/api.php?action=query&list=backlinks&bltitle=Berlin&blfilterredir=redirects&bllimit=50

The response contains 31 items:

</api>

All items are redirects. But only 4 redirect to the article [[de:Berlin]]. The other redirects redirect to other articles. But they contain an invisible link to [[de:Berlin]].

Is this a bug or is there an other API query to get only the redirects to the title?
