Good catch. It's vaguely possible there's a bug in either
shim 15-5
or grub2-efi 2.02-58 as it relates to your firmware, that caused
it to silently fail, and the firmware did a fallback to the 2nd
BootOrder, which is the Ubuntu entry.
I want to emphasize that it was *not* boot order that changed. I
manually attempted to boot Fedora, but it failed (oh how I wish I had
paid attention to the details).
Anyway, I can manually change the boot order to either OS and it
respects my change. My problem was something else entirely since a
manual change didn't boot Fedora.
I may try the manual downgrade, if I get time. I am usually
physically away from this system so I will retrieve the old versions
and be ready when I can get the time.
Again, thank you for your thoughtful follow-ups.
