View a work and click on a tag
The link will go to the /tags/TAG/works page for that tag
Go to preferences and turn on hide warnings/hide additional tags
View the work and show the hidden tags and click on one
The link will go to the /tags/TAG page instead
Never-hidden tags all still go to the /works page.
This should be a quick fix in the show_hidden_tags_link method which is only used for this purpose and can safely be changed to make the url point to a tag's works rather than directly to the tag.
