There are few things missing in you bug report so I assumed them as 1) Your f27 system is updated system by installing latest f27-updates 2) you are running French locale and I used fr_FR.UTF-8 as its easy to set it via region panel of gnome control-center. I now got fresh f27 test system. Installed all those 4 packages and set locale to fr_FR.UTF-8 and ran dnf system upgrade to f28. It downloaded and updated total 1580 packages. Reboot the test system and i can login using gdm to Fedora 28 system. I can see all those 4 packages are there on my system updated to their f28 build rpms. Sorry but I cannot reproduce your problem.
I upgraded from a Fedora 27 updated from latest f27-updates and my locale was set to fr_CH.utf8. After looking in DNF history I see no indications of removing these 4 packages, but they was missing. After installed themes the problem was solved.
This should be the issue with your upgrade. Either its problem of mirrors from where you got F28 packages or dnf failed somewhere while upgrading to F28. You can further investigate it by opening a bug against dnf and providing that dnf transaction log in bug report. I will close this as a NOTABUG.
