[1.9.0] docker-compose v1 - FAILED test/test_virtual-path/test_virtual-paths.py::test_container_hotplug - assert 502 == 404

I noticed that starting with release 1.9.0 the test test/test_virtual-path/test_virtual-paths.py::test_container_hotplug fails with assert 502 == 404.

I ran a git bisect between 1.8.0 and 1.9.0 and it lead to this commit 9ead0cb which bumps docker-gen release from 0.15.1 to 0.16.0.

Docker's version is 20.10.24+dfsg1-1+deb12u1+b2 from Debian 12 (bookworm) amd64. docker-compose is still v1 (1.29.2-3).

I've checked on another Debian box with Debian testing (docker 27.5.1+dfsg4-1 and docker-compose 2.32.4-3) where the test passes.
