For completeness I checked for similar changes since Bionic:
7e77abb9 debian/qemu_2.12+dfsg-2~5 <- ok from Bionic, ok from Eoan/Focal
ce43f003 debian/qemu-3.1+dfsg-3~3 <- This issue
2b5df4f8 debian/qemu_4.1-2~8 <- ok from Bionic, ok from Eoan/Focal
Ok, the reported issue seems to be the only one that really has a bad effect.
