Inverse dependencies or, why a package was automatically installed?

On SUSE Tumbleweed, just updated (2023-08-20) and I have seen in the log a package that for sure I've never manually installed ... (343/370) Installing: trainwreck-5.109.0-1.1.x86_64 .......... [done] ... When I used Debian, I was able to satisfy my curiosity using $ apt rdepends trainwreck trainwreck Reverse Depends: Depends: model-train $ Having googled a little bit, no a substantial bit, the most relevant find shows that it can be done, at least for direct dependencies, but is no help in making one, a clueless one like me, understand how the figures were obtained. How can I obtain at least a list of the reverse dependencies of package trainwreck on Suse Tumbleweed?
