ubuntu folder shows weird behaviour at http://en.archive.ubuntu.com and http://de.archive.ubuntu.com

when you click on ubuntu the tree can become infinitely long. You can click as often as you want:
http://de.archive.ubuntu.com/ubuntu/ubuntu/ubuntu/ubuntu/ubuntu/ubuntu/ubuntu/
I use firefox 146.0.1-1 and Ubuntu 25.10 with kernel 6.18.1
