Hello Santiago, thanks for your bug report. I'm working on a new release of tango-icon-theme that will address this and other bugs, so I might miss the 19th February deadline. However be assured that a new version of Tango icon theme is coming soon, with XDG user folder icons as well!
The new version of tango-icon-theme that will fix this and other bugs will be released at the latest within the end of February 2025. All the best. -- Matteo Bini
