Version-Release number of selected component (if applicable):
dnf5-5.0.6-2.fc38.x86_64
dnf5-5.0.7-20230314005057.17.g160033cc.fc38.x86_64 (currently latest in dnf5-unstable)

How reproducible:
always when run several times (remove downloaded packages between runs)

Steps to Reproduce:
1. dnf5 download rpm-ost\* 
   (have rpm-ost* packages in the same versions in multiple repos)

Actual results:

Every time, five packages were downloaded:
# ll rpm-os*
-rw-r--r--. 1 root root 4233215 Mar 14 03:55 rpm-ostree-2023.2-1.fc38.x86_64.rpm

-rw-r--r--. 1 root root   26685 Mar 14 03:55 rpm-ostree-libs-2023.2-1.fc38.x86_64.rpm


Expected results:
what dnf provides on the same machine (so, not pretending that there are 10 files when there are only 5):
# dnf download rpm-ost\*

Additional info:
* on my f38 machine the packages are available in fedora and updates-testing repos
* related: dnf5 repoquery provides list of duplicates (while dnf not):
# dnf5 repoquery rpm-ostree\*
