As in title: The transclusion filter on Special:WhatLinksHere has no effect. Links (from template transclusions) are always shown, regardless of the transclusion filter setting.
This filter does not work for quite some time meanwhile, I cannot remember when it broke. I am surprised that there is no phab task yet.

Same behavior for all pages, these are only examples. I always see template-transcluded links, although they should be hidden by &hidetrans=1
Well, there are templates with several links in both of these articles. For a long time, the filter was able to hide these links on Special:WhatLinksHere, but for some reason this has changed.
Could you provide an example where the filter works for you? I’d try to find out what happens here…
Can you provide a definite example? That'd make it easier to find the issue.

User:Glaisher/sandbox is hidden when hidetrans=1.
Your example on meta works here as well, I can hide User:Glaisher/sandbox with the filter. Interestingly, User:Glaisher/sandbox is marked as “(transclusion)” when not hidden.
Now back to one of my examples, and let’s focus on the first one from enwiki. The article [[:en:Racing shell]] transcludes templates [[:en:Template:fineboats]] and [[:en:Template:Rowing (sport)]] right in the end as navigation templates. The latter one of the templates includes many links, for instance to [[:en:Dad Vail Regatta]] among many others. This link is not found in the article [[:en:Racing shell]] apart from its transclusion in the navigation template.
So, although [[:en:Dad Vail Regatta]] only appears in a template on [[:en:Racing shell]], the link on [[:en:Special:WhatLinksHere/Racing shell]] is not marked as “(transclusion)”, and it cannot be hidden by the transclusion filter.
hidetrans doesn't hide results with direct links (even if it's on a template), it only hides templates transcluding that page. Feel free to reopen if you think there's a misunderstanding.
Well, then it’s probably indeed a misunderstanding.
However, I am still surprised. Has this functionality been changed in the past (three years)? Can I look it up somewhere? IIRC it worked in the way I outlined above, and I used it regularly.
I don't think the way this work's queries are done has changed recently but you can view the list of changes here. https://github.com/wikimedia/mediawiki/commits/master/includes/specials/SpecialWhatlinkshere.php
