Jonathan, I found some patch, which do "fake online upgrade" on MicroOS from
Dario Faggioli :
https://gitlab.gnome.org/dfaggioli/gnome-software/-/commit/40bfa07198bba0a3c2968162b2ae8b01fd1e29b8

An attempt to add it to gnome-software was successful (with some changes to
make it work in Leap) :
https://build.opensuse.org/package/show/home:milachew:branches:GNOME:STABLE:41/gnome-software

Also, I tried it on a test system with 15.4. Imitated the update of system
components that would require a reboot: changed repo-oss to 15.5, clicked on
the update check button, it was suggested to simply update without rebooting, I
clicked, the update was completed and a re-check of the update found nothing.

At the same time, during the update, the wallpaper became another, and the new
name of the operating system appears in the settings (openSUSE Leap 15.5).
Therefore, I concluded that the patch still works approximately as needed to
fix the problem.

Perhaps it needs to be refined or improved - unfortunately, I do not have the
necessary skills.
But hopefully it can help in fixing the problem.
